It takes money to make money. Can you set yourself up for an early retirement with pocket change?

I've been DCAing for a few years now, but lately have been pretty stagnant since I was laid off in May and was only able to get a job paying $30k less than before. If I put $20-50/month into crypto, namely BTC, can I actually see a difference in years to come or is it just a drop in the bucket? It feels like this type of strategy with smaller money would do better in other coins, similar to penny stocks. Then again, that would be a much riskier game and potentially take longer to see any ROI, not that I'm in a hurry. Do you need to invest big for anything worthwhile to return? I often feel like a tadpole in an ocean of whales.
