Calling him lazy isn't the appropriate word to use on him because he's just human expressing his concern and even if it doesn't make any sense to you it still doesn't mean he's lazy, like you did mentioned crypto actually isn't for everyone and some only get into crypto because they were told it could get them rich so quick so when they eventually get to the point they find out that its way beyond just getting into crypto and you are goin to be rich almost immediately  you see them getting exhausted and burning out already because their expectations are not met almost immediately hence they will just literarily start to complain or make excuses to get them to regret ever getting into crypto but then beyond that if they could exercise some more patient they would eventually get to the point they will eventually get rich as they have envisioned.

Investing in crypto in the real sense isn't for carefree and lazy people who are impatient because investing in crypto actually gets you to be able to get all this in place else yo wouldn't be able to keep up long enough in the crypto space to be able to get as much money as you could from crypto. most crypto investment requires you are patient enough with the process and with time you eventually get to be able to make good money off it as well as you been able to getting used to the whole process and the dynamics of crypto. Duse to the profitability of crypto deals especially when done well, they eventually get to be a major target for fraudster and other hackers online which calls for the vigilance and several security on your asset which will mean you shouldn't be lazy or even nonchalant about the security of your asset else you will eventually get to losoe them to some of these fraudsters and hackers.
