There are supporters of determined HODL, which really only benefits the early adopters.
Because buying late, for example 2 years ago, that is to say end of 2017, and selling nothing in 2018-2019, is already better than 90% of traders, certainly. But it is hardly better as a result of a classic passbook, the risks and stress in addition.
On the contrary (even if it is possible to be part of both profiles simultaneously), there are traders. If you have a little seniority, you know that the border with the gambling (like casino players) is often thin and that less than 10% of traders don't finally liquidate their wallet. Especially with an asset as volatile as Bitcoin.!
Also, I propose here what seems to be a happy medium: the SEMI-HODL.
From only two indicators on long-term scale (therefore logarithmic for visibility):
the MA 150 moving average and the RSI 14. In all simplicity, rigor and efficiency.
This method tells me that the best entries to HODL must be made by a massive buy when RSI 14 <30.
Historically on Bitcoin, it was therefore January 10, 2015 and December 15, 2018 (see my related ideas).
Then, it is important to take profits (TP) gradually every time the RSI 14 exceeds 80.
This represented 4 TPs on the previous bullrun near the top of each parable. To be repeated at the next bullrun.
Attention: if you have not yet released all these profits, according to my method must imperatively sell your BTC remaining when RSI 14 goes under 50! On the previous Bitcoin bubble, this represented a final sale (if not already done) at the end of January 2018 when BTC = about $ 10,000 (still in x40 since the Best Buy, 3 years earlier).
