In Mexico we have Bitso as the most convenient way to exchange our cryptoactives, BTC, ETH, LTC, BCH and RIPPLE, they are the crypto that we can exchange for Fiat money.
I do not know if I can trust 100% in them, their exchange system is very fast the sending from Bitso anywhere is very fast, it works 24/7, but even so I do not have all my crypts in this site, do not distrust of dawn one day they were hacked and we lost everything.
Another thing that does not give me a good spine is that the Mexican government I think has spoken with people from Bitso, have asked for information from their clients and I wonder what would happen in the future that want to impose taxes for having cryptocurrencies, surely with our personal information they can make us pay these taxes or we will be forced to its regulations.
In wikipedia I read that Steemit emerged under anarchist ideals and it is very true a self-regulated system without government and an option of un-traded exchange in mexico so far I do not believe it exists.
Greetings and make it the best of your days
