I should say trading view is really great and I have already used it some time, now back when I was trading with Gold, and other Fiat Currency, I got Charts, Research, and Analysis for you to see, and got a notification alert so you will not miss your opportunity, And you can certainly trade a limited Cryptocurrency as well with paper trading.

But If you are looking for a radical one that focuses more on Cryptocurrency I suggest Binance, Because I am using it as well and it works like a charm.
