Ledger wallets are full of flaws. I am expecting another flaw again but some people will not listen until they are affected. I will like to say that DeFi, DAO, Dapps and other innovations are just another way to give scammers privilege to do their work.
DeFi projects with low secured protection suffered so many uncountable hacks this year, a lot of victims felt frustrated from this hack and it's really sucks.
The question here, how will you know a DeFi platform is highly govern with high security standards, even big centralized exchange got hacked couple of years ago, what to 100% completely trust at this moment, nothing to think.
