Did you really double your BTC or your BTC value converted to fiat?
That's what I am thinking about.
This is very different.

However, I congratulate you to get that high profits after converted to fiat. Buying and holding BTC will be always risky, however, sometimes, this will also bring high profits if cashing out at a higher rate.

And about the current price of BT that is more than 45%, I think it is no matter, as long as you have reached your target at 30k, it is enough. At that time, you may not know that the price of BTC will be really high like now, And selling BTC at 30k, getting that many profits are good enough, no wonder that the price is now increased again.
