the point is that whenever you want to enter a market you do it when things are calm and at the bottom not when the rise has started. it is not meant as a regret but something to keep in mind for future decisions.
That's simply not true. Most people who try to call the bottom during a downtrend are wrong and the price will keep dumping on them.
You were proclaiming the bottom was already in back in August/September last year:
To those saying sub 10K bitcoin is over. RUN!!! Those people are fools.
sub $10k IS over.Now you are scolding the OP for not buying in the $6,000s?
It's very reasonable to wait for a confirmed bull market on the higher time frames before buying in, and especially before leveraging long.
