According to me The best ways to grow your BTC is by trading. You can multiply your principal amount in few days of trading and your profit margins can be terrific. But remember that trading is a risky and unpredictable job.
You can also grow your Bitcoin by investing it in various new projects.
Yes I agree with you
If you want to grow bitcoin play trading
I think investing bitcoin takes a long time to get a great profit like trading.
Trading can indeed make bitcoin growth very quickly, even faster than investment. But it can also be a bomerang, that is, it can also make your bitcoin less, due to lack of experience and inadvertence.
