i use coinbase wallet (its called "coinbase wallet", its separate from coinbase but same company obviously, you buy ETH on coinbase, send it to wallet, and then on ur computer you go to uniswap, link ur wallet, and you can convert ETH to ETH-based coins (MCDC is one)). so in short you buy ETH on coinbase, transfer ETH to wallet, hook up wallet to uniswap, and then swap the ETH to MCDC (press add custom coin or whatever. the address is on the website https://mcdcoin.finance/
this is the address of mcdc:
press add and then swap it. also set the bullshit option increased from 0.5% or it might fucking fail to transaction and waste your gas. im retarded so i made mine 5% cos i cant be bothered with that.
here's all the relevant websites:
