Somehow I do not agree with this strategy as we've seen many times coin dumps close 100% and never come back up, by then you just get a whole bunch of shitcoins with almost zero value.

I've tried many ways in implementing different strategies which is able to "hold" its value and one of the most effective NONE DEGEN ways to it is with a delta neutral hedge between spot and options trade where you buy and option call on BTC each time it goes down 3% you then gain interest if the price at settlement if its above buy price and its below you reinvest in a covered gain and earn interest until BTC shoot up above price. So far this has gain me around 78% in 2 years. Yes there are many other more "risky investments" with better returns, however this is one of the "slow and stable investments" which has proven thru multiple pumps and dumps.
Just my personal opinions .. cheers =)
