Thanks for the great comments.

You are correct I am primarily talking about Bitcoin and some of the crazy going on there with the potential for a Bitcoin bubble bursting and bringing the rest of the market down with it. There are risks on the periphery but anything that hits Bitcoin hard will hurt everything.

I personally would like to see Bitcoin pushed aside, some of these obvious scams flushed out and money can then flow into the newer innovative cryptos that can take the market and technology forward. I doubt it could every be an orderly transition though so that is why I am cautious off a boom-bust transition.
