I'm at Bitfinex at the moment, however I'm thinking of going back to Binance; giving me more options for stable coins.
Please do not keep your coins in an exchange. If anything happens to the exchange then you are going to lose the asset.
I'm currently all in tether... which isn't a good idea currently IMO.
This is certainly not a good idea. Why not have BTC and store them in you own wallet which private key is only accessible by you.
Is that a valid concern?
This is
seriously a valid concern
