I know that there are many kinds of alternative coins existing today, but is it better to have that many coins instead of having just a few? What are the benefits and harm in having that many alternative coins?
do you mean the coin earned from the prize ??
if it is like that, then I think saving a lot of coins is not a disadvantage, instead we have many opportunities to profit more.
I also have a lot of coins earned from bounty, sometimes if a coin does not have a price, after a few months the price gets better and makes me lucky.
yes, I never sell my bounty tokens before I hold it for a good time. Majority of them I plan to hold few years and then only will consider to sell and see what profit I have made
