I don't know if I have argued with you regarding this, but your statement is correct. The risk was higher before, but Bitcoin investment is not risky compared to how it was back in 2011. Even though it's not risky today, I won't suggest anyone invest all their capital in Bitcoin because we don't know how long we will be in the bear market.
Bitcoin usually gives you profit in the long run, but believe me, not everyone has the patience to wait that long. Most of them will end up selling their shares and blame their mentors after waiting a couple of months or one or two years.
If someone understands Bitcoin on their own, they can invest whatever amount they want, and they won't have anyone to blame
