Why would you get out of bitcoin BEFORE it's parabolic rise? I must be missing something.
The long term goal would be to increase one's bitcoin portfolio. The reasoning is that over the past few runs, when bitcoin gets on a parabolic rise versus fiat, altcoins rise significantly versus bitcoin. In between, the alts tend to fall versus bitcoin.
Once again, there's part of me that is not exactly "proud" of this strategy; it's game playing, and I see myself as an investor, not a speculator, in crypto. So I only do it with a very small fraction of my bitcoin investment. In a way, I see it as a test of whether I think I can outguess the crypto market.
