No one knows! When we do talk about recovery of prices then no trader or man can able to point it out which this thing is really impossible.When you do ask if its wise to switch to bitcoin then its your choice but if i do have still funds to invest then choose both since you do mentioned you hold stratis since 2017 then dont sell out those coins but rather add up funds on buying btc while its still cheap. When market recovers then it would be a win win situation for you since those 2 coins will really increase.
