OP, just know that at every buying point there's also a selling point. Though you bought slightly at a late time you're enjoying the dividends in price rise now. You took that risk and it paid off. You've to realize that there are people who will still buy at the peak of this bull run and suffer the dump. However, I don't see any Bitcoin dump happening any time soon within this first quarters of 2021 (even into the 2nd quarters). We may see corrections here and there from time to time but definitely price will continue to rally up after each correction. The trend is upward at the moment. 2017 should be a reliable place to look as history is always fond of repeating itself.
