I think it's worth taking a closer look at altcoins and not getting hung up on bitcoin alone, especially if the amount of money to invest is less than the cost of one bitcoin. Bitcoin will grow gradually, that is, for months you will have to wait for its price to double, while alternative cryptocurrencies can grow in price dozens of times per week, especially since there are now a large number of promising projects.
indeed, if we look at bitcoin today, of course there is a sense of regret, but indeed by investing in a potential altcoin, we can still get a big chance of profit, but we have to be more careful to identify it, because bitcoin is indeed the safest coin to invest in.
