As Spencer Bogart of Blockchain Capital sees it, a secondary layer on Bitcoin ($BTC), like Lightning, is only the beginning. Lightning innovated and expanded on payment channels for Bitcoin opening up transactions to multiple users in a seamless way. As the number of blocks on the Bitcoin stack increases, the potential for practical systems should grow exponentially. These new systems will be of both centralized and decentralized nature: practical tools, programs, or services taking advantage of the first programmable money. Like the internet in the rotary age, we cannot see where the market will take Bitcoin. All we can do is recognize the enormous potential and invest accordingly.
