Maybe there are a lot of other trading algorithms that worked for some time but ended with a loss so big that exceeded all the profits, and we will never see those stats. Publisher bias.
That's what I think is quaint about all these people who came up with crypto buying strategies. The naive "just buy as much as as you can" strategy was very effective until January.
It was effective but not optimal. Some people were overjoyed with their 10x on Ethereum, while others were getting 100x on tokens. It was also obviously highly non-optimal if you held through January :)
