The ground you walk on is slippery, and just when you think you are standing stable, you slip and fall. Getting up is of course a difficult process, especially for those who cannot afford to lose $35k and start all over again. However, I would emphasize here that the key thing is to learn from your mistakes, and although I generally understand the need of some investors to invest in "numerous difference projects", I cannot escape the impression that they are making the same mistake again and again.

9 out of 10 such projects will fail in the long term (in less than 4 years), so it all boils down to the perfect timing of when to buy and when to sell. Everything else is speculation, including the fact that the price of Bitcoin must fall below $15k, which is not impossible, but there is also a high probability that it will not happen.
