Lightning, the technology discussed in the article, solves this problem.
> As with most layer-2 solutions, Lightning seeks to increase transaction throughput and lower costs while retaining sufficient decentralization by moving activity to a second network. Once BTC is on the Lightning network, it can be transacted instantly typically at fractions of a penny.
> Rather than expensively sending each transaction over the Bitcoin blockchain, users deposit BTC into the Lightning Network and then transact inexpensively through payment channels. As with most networks, the more people and companies that join, the more useful it becomes.
