Ever favorite
BTC,
ETH, and also
LTC . That's my top 3 but i still have more tokens i am trading at right now. Also looking for a new ones is also good thing to do.
Yes, but the three tokens and coins that have been your favorites are always good all the time and also are still favored by everyone who is in crypto, so if you don't look for anything else I don't think it is a problem.
