Etherium has serious potential as a distributed network, and as a networked means of greatly enhancing transaction and contract efficiency. I think we are seeing just the tip of the tip of its iceberg.<p>Bitcoin concerns me. If/when BTC is makes its appearance in the every day lives of ordinary people, its anonymity value will have eroded significantly. Traditional currencies have not yet started to compete with BTC, but they can and they will if necessary. Try getting a mortgage, car loan, business loan with BTC as collateral as one example of where my concerns rest. Look at the grossly inverted price of BTC and gold prices (artificially assuming 1BTC = 1Oz).<p>Before BTC there was growing dissatisfaction with money center currencies that persists today. BTC 'took the edge off' for many in those circles and may have relieved pressure on gold prices.<p>I don't necessarily believe this, but I've read in economic revisionist circles that BTC would be means for certain central banks to redirect some demand and attention for precious metals away from their vaults and toward an asset class they, better than anyone, are capable of mining with their existing computing infrastructure. So, by invention or acquiescence, BTC serves money center interests, for now, but not indefinitely.<p>BTC remains a highly speculative and risky asset/network in my mind.
