Crypto is everywhere now, but I'm struggling with how to actually use it. Do people really use Bitcoin for coffee and donations, or do we mainly see it as a long-term investment? Is it practical for everyday use now, or should I still just store it away as an asset?

The ADA in my old MetaMask wallet needs to be migrated, and it needs $0.02 in ADA gas, but the funds aren't showing up. Since my crypto is on the ETH and Solana chains, how do I get this little ADA sum into my wallet the simplest?
