Advice, tips, speculation please.
OP posted this when price was around $450. today it is @ $1147. that is +250% in 10 months.
first sentence in first answer nailed it:
Keep 12 BTC and wait...

Yeah. If he still holds his Bitcoin upto now, he will probably earn more than 250% from his capital. Have you seen the utility of bitcoin yet? That is why i will keep hold my Bitcoin for another 4 years. I am very exciting to know that Bitcoin have crossed over $1000. Damn it. I should buy more Bitcoin.
that is sadly why we all end up doing. we just turn into 100% investors who just hold bitcoin to sell at some point and take the fiat to use. and bitcoin stops being a currency if we continue this way and price will also take a big hit if this happens.
op clearly asked for investment advice. if we all stop investing in btc, what do you think would happen to the price? another important point is that in order to reach mass adoption, price must be way higher than now. so no, not sad but good. if price is high, utility will develop.
If there is a mass adoption then it will directly contribute to the higher price of bitcoin and the demand of bitcoin is increasing at a moment and that is the reason price is climbing up and it will go even higher when more people will invest their money in bitcoins.
