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.
