Ultimately, this is totally up to you. And it depends on your risk tolerance level, so we can't make a generalization about whether you should invest with small or large capital. If you can handle some big losses, get in with more money. If you're risk averse and unable to recover from big losses, you may want to get started with small investments. However, that's just my opinion from my own experience. Everyone will have their own differing views on this subject.
Before you make any investment decisions, always do your research and plan ahead. Take the time to look into the potential risks and rewards, examine which cryptocurrencies are worth investing in, and create a strategy that lets you ride out any bumps along the way. Regardless of the amount you decide to invest, your due diligence is crucial. Good luck!
