My old coins is still Ethereum and some XLM and Dogecoins, For token i currently holding WPP and ShareRing this token is from bounty last year.
For the old coins you choose, I think it is still good to be maintained for a long time, but for the two more coins that you get from the bounty, there doesn't seem to be any good potential in the future, due to competition between new tokens on the market. crypto already very much.
