During last time do a lot of bounties and get some different price. its near 17 numbers and all price according to the market no more then 350 USD for all... What you should recommend to do with this coins?
I recommend for you to trade those coins. Make them grow especially those potential coins. If they are already listed and have value, sell them at very good price and buy at cheap price. Also, you can just hold them until their platform becomes fully operational.
