You have the choice between a free, transparent, technically stable, instant payment system (< 10 seconds until 100'000 EUR), using a stable currency.
or
an unregulated system where unknown people create and control the currency, that is generally slow, often with high payment or exchange fees and where you need to trust a lot of unknown parties (software, tools, network, coins, etc), where you can lose your key, that is falsely transparent (you see transactions, but you don't know who control the network).
Mhhh...
