I suppose I might say that's a decent beginning. Please keep in mind that not all Bitcoin investments result in profits; some losses, perhaps even sizable ones, can happen because the cryptocurrency market is unstable. Just keep buying Bitcoin if you have additional cash, and only then should you hold onto it for a long time.
Market is stable over long time periods. The yearly swing is less than 15% but on short time periods it might seen to be more volatile. Like now the price is back to 27k which is a correction happening after the bullish swing. These ups and downs are how the market keeps itself active and it is upto you how you want to capitalize on it. You might want to play it safe and wait for the price to go back to 25k before buying again or you can buy a smaller fraction now and wait for more drops when you can buy again or sell if the price rises.
It is tough to execute, I agree but traders need to get the hang of it over time. Again not everyone will manage to profit from this.
