Is $10 enough to invest in crypto?

I'm curious, is $10 really enough to make a meaningful investment in cryptocurrency? With the volatility of the market and the high prices of some coins, it seems like a small amount might not go very far. But on the other hand, I've heard about micro-investing and fractional shares, so maybe it's possible to start small and build up over time. What's your take on this? Is $10 a viable starting point for someone looking to get into the crypto world?
