I've read about how BTCUSDT is some kind of token tied to the dollar
BTCUSDT isn't a token. USDT is a token (that is claimed to be) pegged to dollar.
BTCUSDT means bitcoin price / USDT price rate.
Assuming each USDT token is worth 1 dollar, BTCUSDT means bitcoin price in dollars.
So, following BTCUSD seems to make sense to a newbie like me. But, then I keep seeing youtubers watching BTCUSDT in their tradingview screens.
No problem. There shouldn't be a big difference.
Note that even if you look at BTCUSD at two different exchanges, you will see that the price isn't exactly the same.
Am I okay watching BTCUSD for trading a little bitcoin in robinhood as a total noob? Thanks
If you only want to see the price, yes. It's OK.
There shouldn't be a big difference between the price shown there and other exchanges.
If you want to buy bitcoin from robinhood, you should notice their commissions too, especially if you want to buy a low amount of bitcoin.
