I like to buy a coin and move it off the exchange to a wallet under my control.  My question to you is what do you do when you get a new coin that is not supported by a cold wallet or desktop wallet and the company has not created their own wallet to store the currency?  For instance if I want to buy tron and don't want to keep it on the exchange where I got it from where can I put it?  What wallet can I use?  This goes for many of the new coins that are valued at under .05 USD.

Thanks for the replies
