Web Based .IO Game Supporting Transactions -- 2

I would like to create a web based Battle Royale game built on Node.js and javascript primarily. The game needs to be able to host multiple servers, and grow seamlessly and easily if the player base increases. On a server, 100 players need to be able to connect and play with little to no lag to increase fairness of the game. The game needs a front-page (for logging in, about, etc) and obviously a backend for the actual gameplay. Users should be able to create accounts and log into them relatively easily by being able to save passwords through cookies. Another large portion of this project is to have some sort of plugin for accepting payments and receiving withdrawals to banks, or more importantly, through digital wallets using cryptocurrency such as Ethereum or Bitcoin. Additionally, I would like to be able to present ads to the player base randomly or perhaps when joining one of the games.
