I would also like to add that you should always remember that you need to leave money for everyday expenses, because many investors make a mistake: they want to quickly accumulate more Bitcoins, and therefore allocate too much of their Fiat for buying at DCA, after which they do not have enough to live on. And they have to withdraw cryptocurrencies back into fiat,
Lots of people do make this kind of mistake. When making investments, we are supposed to always have emergency funds, we shouldn’t invest everything we have, we should have money that will be used for daily activities and some amount that will serve as emergency funds. In case anything happens, you will be able to take from that to solve the problem without even touching your investment, but if you invest everything you have, you will end up selling when you are in need of money. Investing everything you have is not a sign that you are really serious with your investment, if you invest everything you have, you might end up selling most of it, and it might be at a loss.
