The tradeoff is always between inflation (block subsidy) and fees and Bitcoin is the best positioned to charge fees reliably. If there is no economic (transaction) volume in 10 years bitcoin will have failed anyway. Stacks leverages Bitcoin’s Proof of Work consensus for security, which uses the combined efforts of thousands of miners and nodes to protect the network against how does investing in bitcoin work attack – primarily by making it unfeasible to undermine the network, both in terms of computing power and in terms of financial incentive.
