The established alts, such as ETH and ADA made the recovery, but the smaller alts and tokens never recovered from the slump in 2018. Most of them are now dead or dormant.
Some of the alts that showed potential never recovered and there is no hope whether we will have any decent profit as some of projects stopped developing when the market went down.
@OP It is not the best time to invest as all the markets are rallying at an all time high valuation, like everyone mentioned we saw rally recently in BNB and ETH might rally even though the transaction charges are high.
