One thing, i see is that almost everyone does, but it seems that they are persistent in admitting the mistakes they make. In this market there are many options to invest and bring high returns, but review this to see what i say is not wrong. If you use all your money to invest in btc then the profit will be better than using that money to invest in altcoins, realized this when i sold btc and bought altcoin, i saw the asset their own does not increase but decrease. Maybe it depends on the timing as well as the amount of money that you will spend, but nonetheless, it is also an advice for you.
