I had Bitcoins in 2013 back when it was $50 and then lost them daytrading on margin at BitFinex. Would have 500x my money in several years.
Listen the rule is simple:
1. After a crash, buy BTC and just forget about it until some alert that BTC has exploded 5x or more
2. If BTC had a big run up, buy ETH instead
3. If ETH had a big run up, next buy XRP
4. If XRP had a big run up, then escape into tethers and wait for crash
Repeat :)
If you did this sequence the last few times then ONE bull run nets you 5 x 5 x 5 returns!
