Don't select 1 altcoin, but create a basket of altcoins. It would be much more better, because I stick to rule, don't rely on 1 alts, even it is ethereum or another top crypto.
Don't hold on and hope that one coin can make a profit, I think it's just a waste of time because there are hundreds of other coins that also have good potential if we invest.
storing a number of altcoins in a portfolio is the best solution to being able to get many benefits because basically, each coin has a different price, movement, vision and market capitalization, so we can benefit from one of the coins that is increasing while waiting for other coins which has not risen in price from the time we bought it.
