Yeah. If for no other reason, the market volatility can lose you some money. Sucks having btc when a darknet market gets busted. Nothing like btc losing 40% value in fifteen minutes. . .
That's not going to fool Coinbase or anyone else. Unless the third-party wallet is Dark Wallet or a wallet with some other implementation of Coinjoin. And even that's not foolproof.I guess in a nutshell buy the coins from either coinbase or circle then transfer to a wallet of your choice? From the wallet go about your business to buy protein powder?
Good advice there.The latter can be verified by anyone by simply sending the vial in for testing.
Not so when it comes to a vendor's claims about the bitcoin security you mentioned.
At best, consumers can look at the address given to them by a vendor to see if it is new, never used before. If it's not, be careful.
