I bought a bitcoin what 0.0003 BTC last year November with only money that left with me when I finished my program and named it investments, many of my friends started laughing that my money has gone and bitcoin will fall and is out of surprised bitcoin moved to 19k, 20k, 30k and 40k, so I'm excited for having double of my btc within some months, I want to know if I will sell it or withdraw it, because is a investment money not for spending.
You are lucky ( even it is small amount) because you hold a bitcoin when time that has low price and now I think it's your time to trade because you have sure profit. Don't be greedy, be satisfy in the result. We will not predict the market of cryptocurrency in the future. It possible that the next pumping of bitcoin will be next 1 or 2 years and again we need to wait for good profit.
But I like your strategy, small amount for investing only, even it will not become successful or earn huge profit it just small. But the successful person started in small capital.
