Back in 2017, much of the focus was on altcoins as there was an ICO boom. But the same altcoins, which gave 100x or 200x returns during the first half of 2017 went down by as much as 95% or even 99% in 2018. Almost everyone ended up with losses, and some of my tokens and alts also went down by a lot. 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.
