Crypto Question: Best Strategy for Crypto Buy?

Hey everyone,

I’m new to the world of cryptocurrency and trying to figure out the best approach for a crypto buy. With so many options and volatility in the market, I'm unsure where to start. Should I focus on established coins like Bitcoin and Ethereum, or are there promising altcoins worth considering? Additionally, is it better to invest a lump sum all at once or use dollar-cost averaging over time? Any tips or strategies you’ve found effective would be greatly appreciated. Looking forward to your insights!

Thanks in advance!
