That's it, the future of cryptos will be about patents, development, and commercial wars, and only the big ones will win. It's up to people to wake up if they really want cryptos to be free from banks (and even to be able to use for some countries...)
that will only be a "part" of the future not the future of cryptocurrencies!
the technology has been open source and will remain that way, and because of it you can't change much about the innovations and the real development that takes place in this technology. what they patent is only a small part of it which we can live without.
