If I wanted to create my own altcoin, what is the easiest/fastest/cheapest way to do it?
By "create" here I mean a coin I could give to my friends, offer to trade for other altcoins, and store in a wallet.
So you are looking for ways to scam your friends or their money, more than 5000 tokens were launched in the past 24 hours on Solana, it depends on where you want to launch the tokens, there are tutorials on YouTube on how to do it on Ethereum, and I am sure there should be one also for Solana since both platform are the two big thing in the space for now. I won't advise you create one because you know nothing about blockchain
