I have an old account with TD Ameritrade - and money leftover in that account - and mistakenly believed I could buy crypto. What's a safe platform (understanding that "safe" is a relative term) to make a purchase?
Is Coinbase the consensus platform?
Something else?
I use Swyftx, but its probably just Australian.
Here is the most important tip, ignore it at your own peril. No matter what platform you use to purchase crypto, always move it to your own personal wallet. Anything you leave on the exchange is 1. does not belong to you and will be used against us 2. you can lose it at the drop of a hat.
Ideally you should use a well protected paper wallet, but a decent hardware wallet will do (Personally I dont trust hardware wallets, but the consensus here is, its safe)
Even if you dont have either of this and want to purchase crypto quickly, install Exodus on a computer (or mobile if really necessary) and withdraw all the crypto out of the exchange to the Exodus wallet.
