These guys want people to 'securely' store their #Bitcoin in the wallets provided by exchanges!!
There is so much of misinformation being spread about bitcoin
A : Bitcoin(UTXOs) are 'stored' on the block chain and not in wallets. It's only the keys that are stored in the wallets.
B : Never leave your bitcoins on the exchanges, move them immediately to a FOSS self custodial bitcoin hardware wallet.
