I don't (usually), and never would with internet ledger numbers hosted by strangers I have no way of holding accountable. I have invested a little over 400.00 (and a shit load of time). I pulled most of it out and spread to another project that might be a better risk, but with the clamp down here in the US who knows. It might all become worthless once the dictators tell the cattle whether they can own it and if so how much it will cost to move it around.
