This is the only to ensure that no people will be cutting trees illegally. How this can be achieved. By tracking the source of each wood made product.Making a national or state level Supply Chain Management System for Forest Department which can track trees , it’s cutting and it’s final product. This will ensure that how much stock supplier have , how he proceed the wood , any thing else will come under the subject of law and action can be taken against him. Eliminating trees cutting over a period of time. Even the plantation and seeds can be tracked to give good values to the cut down trees.  Such a big Supply Chain to End Product is only possible thorough Block Chain for Forest.” Block Chain for Forest Detail Explanation of Solutions   Many Corp-orates around the globe are using Block Chain to manage supply chain. Block Chain ensures the records in digital system are as good as signed document. With the help of Block Chain companies can track the exact origin of product. Origin of all the raw material is tracked as well to ensure the good product. Tracking origin of product and raw material ensures that all the product is coming form good and authentic source. Same principle can be applied for Wooden Products , which can be used to track the origin of Raw Material i.e Trees. With Block Chain in places government will know who owns the woods and who has produced the final. If Some one who have not purchased the wood from authorized vendor or department will be cached in the eyes of authority and respective action can be taken by the Government Agencies.

To Give worldwide exposure to our coin To get Listing in Coin Market Cap Let’s get directly to the quantitative analysis. See the table below Exchange Name Total Volume Low Volume Coin (Less than 0.001 BTC) Percentage of Total Poloniex.com 4000 BTC 3 < 1% Binance.com 154704 BTC 10 <1% HitBtc.com 40582 BTC 50 > 30% Yobit.net 3731 BTC 70+ >50% Mercatox.com 800 BTC 50+ >50% Stocks.exchange 32 BTC 100 > 60% BitRidex.com 250 BTC 3 >50% Cryptocrix.net Not Known 3 >80%   Above table clearly shows that  considering the exception of Poloniex and Binanace , it’s clear that Coin Listing in Big Exchanges doesn’t guarantees that coin will be purchase on huge volume. Even in very big exchanges there are coins which don’t have enough volume. Coin volumes mainly depends on following factor How much big is the community How much active is the development team How many places where coin is readily accepts as other form of payment How Strong is the technicalities of the coin. How strongly it’s being promoted and it’s being brought in the attention of Crypto Users. Time Taken to Grow on the Exchanges After coin is being listed on the exchanges , it’s not wait and watch. Lot of efforts need to put up to get the users attention. To do self sell and purchase and buy more coins , this needs to be done to pump up the rate. Coin dumping needs to be avoided to maintain the rates.Need to ensure private source code or heavy mining machine. Because Crypto Miners immediately start mining and sell them when the price is right. They may even start dumping the coin. After all the above steps are taken post listin the coins , lets see how much time is required to attend the organic 1 BTC Volume. Without our own pumpers. Time Taken By Exchanges to Reach 1 BTC Volume in Organic Way No Pumping by Founders Exchange Name Total Volume Time in Months Comments Poloniex.com 4000 BTC 3-4 Months No Guarantee but chances are high Binance.com 154704 BTC 3-4 Months No Guarantee but chances are high HitBtc.com 40582 BTC 6-7 Months No Guarantee.

Cryptocrix.net Not Known – No Guarantee   Above analysis clears that reaching volume is again off line work , it’s like promoting coin to international users. International Crypto Users are not fool to buy the coin , just seeing them on Exchange. Lot of other efforts are required , main in marketing and technical upgrade of coins on regular basis.   Pros and Cons of Exchanges Lets analyse the pros and cons of reference exchanges and see where we fit.   Exchange Total Volume Pros Cons Poloniex.com 4000 BTC High Volume , Listed on Cryptomarket , Good User Base Check  Criteria , many coins don’t fit here Binance.com 154704 BTC High Volume , Listed on Cryptomarket , Good User Base Check  Criteria , many coins don’t fit here HitBtc.com 40582 BTC High Volume , Listed on Cryptomarket , Good User Base Many coins are listed , No attention to small coins , high listing fee of upto 10-25 BTC Yobit.net 3731 BTC High Volume , Very High User Base , Listed in Cryptocompare Bad Support , Many Coins without Volume , No Attention to Small Coins Mercatox.com 800 BTC Average Volume , Average User Base , Listed in Cryptocompare Many Coins with 0 volume , No Support from Exchange related to Coin Boost Up.
