Well I was told to invest when BTC was $14 and I had £5k to put in to it.
I read up on it all, got excited, tried to join a few websites to trade, found that it wasn't actually that easy to get your money in to them as they were foreign, especially as I was GBP, then sort of gave up and forgot about it all for a few months.

Then my mate who told me about them in the first place (actually I think I had heard about Bitcoins ages ago) and mines them reminded me about them when they were $200 or so. I looked in to it again then saw them crash to $90 so thought 'man this is a volatile business to be in' so didn't do anything about them again! Then after keeping an eye on them for a few months and doing even more research and found a couple of good UK based trading sites like Bitbargain and Bittylicious eventually bought a few at about £500. Then saw them go up to £800 or so for a week then they crashed through December!

But I'm in it for the long haul now. Although I do think that eventually a different coin or system will be the one that is adopted by the world in the not too distant future. But I do believe this is the future. Like why wouldn't we adopt this system.
Why give our money to banks for them to gamble with and make huge profits out of while giving up 0% on our accounts, actually they even charge now for most accounts.
Although I think that banks and fiat could work alongside each other. We use crypto for our savings and money we want to control and spend and fiat we give to the banks and say okay if you want to leverage it up x10 and basically gamble with it then okay but our returns/interest should be much higher.

Anyway now I've got a few hundred of about 10 different coins and am hedging for a few years to see which one takes off. Nxt and eMunie get my vote right now.
