I have a reasonable understanding, I just don't trust the systems around it. At the moment it's like the wild west was with conventional money. If I put my money in a bank and the bank gets robbed I lose my money, so the banks installed ever more security measures and guarantees until people are confident about putting money in a "bank". Currently bitcoin is in the wild west stage when they mature a bit they may well be a viable currency, for now though I'll pass.
Most currencies are underpinned by a guarantee though, aren't they, 3T? Not just secure storage? There is usually a central issuing bank that "guarantees to pay the bearer on demand".
Still cannot quite understand what underpins bitcoins.
Yes LG that's the point but go back to 19th century wild west and if the bank got robbed you lost your dosh. The money was is still underpinned, buy gold usually, at the time. Bit coins are underpinned by mining effort primarily. To be fair though most modern currency is not underpinned at all, what with QE etc, it's just computers keeping the score
Bitcoins like roulette, they started from 00000.1 USD per bitcoin -> rise to near 1000USD, and now 476. So who know, maybe tomorrow they will rise again. This currency is not save for trading, but its easy to earn, hardware for $10000 gives you 1-2 coin per week, so after month you get profit, some graphs http://mining-profit.com/
