I think what happened to BNB is proof that POS are not decentralized but they are centralized. I hereby reinforce my own reasons for only investing long term in bitcoin. many altcoins are, in fact, centralized. even if they say it's not centered. and the Hack incident that just happened to BNB really made some people doubt about BNB. but myself if it is for short term then no problem. and other beginners I think will think the same.
