The total market capitalisation tells another story. No worry.
The resources invested in the mining infrastructure entitle bitcoin the monopoly status, the computing power running bitcoin dwarfing the total existing banking system by a great great amount. This is "the one" at least for now and quite some time ahead. Banks are scrambling investing in blockchain technology cryptocurrencys for inter bank and central banking clearing now, effort is fragmented and maybe too late. Worry about the dollars first.
