Yes i think your information will be correct. I also think in future Bitcoin will fly and It's price will increase unbelievable way. Because Bitcoin is very popular now for investment. And you choose coinbase for hold your Bitcoin it is also good i think. Also BTC-USD is good pare. If you hold Bitcoin now i think in future it will give you big profit there has no doubt. But my advice you can do DCA it is best way for cryptocurrency investment. When price will down then you can buy Bitcoin. I think DCA will help you to reduce loss and within short time it made profit.
