Don't worry they will come to invest on the cryptocurrencies when they see the sign of bull run and again they will jump to something so they will keep doing that, don't care about them bro.
Just let them do, anyways they are free of what they want for their life. It could be their regrets for not being a part of crypto journey, they are worried for the collapse scenarios happen but they are wrong. But I believe they turn back into crypto when our market turn into good even not showing bull runs.
