For sure if I successfully make a good amount of profit here in cryptocurrency or Bitcoin, I would probably reinvest again in the future if I get a good opportunity on the next cycle but personally, the goal is to buy a more safe asset something like a real state, or a passive income like an apartment, or maybe something like a resort, etc.
Re-invest your money is only good if after you got big profit with your initial capital, you did withdraw your initial capital as your saving. After that you can start your re-investing with profit you got and you will consider that profit as your new capital. The initial capital should be stored as your saving, untouched through your re-investing process.
If you re-invest with your initial capital and your profit, you will have risk to lose them all with one or few bad investments.
