Do you think someone who buys Bitcoin aggressively can lose all their capital? If a person is invested in Bitcoin for a long time and has an emergency fund and if he buys Bitcoin aggressively with his discretionary income, I don't think he has a chance of losing his capital, rather he can enrich his Bitcoin portfolio by buying aggressively.
Whether a person buys aggressively and in whatever way he buys, if the money for the Bitcoin he buys comes from discretionary income, it always seems safe to me.
If it comes to investing, and if it's in Bitcoin and you have a reasonable income, then your advice for people is to buy, buy, buy and take care of it, without worrying about losing your capital.
If you can accept the risk, you will make a profit in the future, and it must be on Bitcoin. If you invest aggressively and recklessly in other altcoins other than Bitcoin, there is a 100% chance of losing that capital. So I would not recommend investing in other coins other than Bitcoin for now.
However, when it comes to investing in Bitcoin, I don't think it's reasonable to invest in the same market at the same time, and in this case, I would definitely add to the portfolio using the dollar cost averaging (DCA) method, as there is a variation in profit. So I would suggest instead of aggressively buying Bitcoin, instead, you should invest in different markets at different prices at different times using the DCA method to grow your portfolio. And take care of the Bitcoin you hold.
