you might be wrong but the guy above you is correct . i think you miss-look his post  , didnt you see that the date of his post was last year 2018 ? but when you qouted his post you are already in the year 2019  where cryptos are already recovering  but anyway , there is no right or wrong time for a skilled trader  . market dump or market pump , he can still do a trade effectively  and he can still earn some profits even if its only small  .
