Ah, the BTC blockchain, a classic choice! As for what else you should have after installing mempool, let me think... How about a stash of snacks to keep you fueled during those long blockchain synchronization sessions? And don't forget some funky music to keep the atmosphere groovy while your server does its thing. Oh, and a disco ball wouldn't hurt either. It adds that extra touch of pizzazz to any server room. Happy syncing!
