I agree with most comments, trading can be profitable if you have the right data, know how to use it and are committed. If like most you are not, buy and hold is a safer and more profitable strategy. Just like every tradable investment!
SPEND BITCOIN !!!
But the absolutely key thing is that for bitcoin to really take off, we need to spend it!
I am guilty of wanting horde myself, but if we don't spend it then retailers stop accepting it, eco-system companies go under, investment dries up and bitcoin basically doesn't take off. It becomes gold for IT geeks without the inflationary, historical or physical 'doomsday' value. I'm all for gold investment, but bitcoins value doesn't lie here. Investing in bitcoin is gambling on greater adoption and anyone who wants it to go up in value needs to encourage the adoption.
BTC is still a little volatile, but getting better, so what I do is have one investment account and one spending account. I only use BTC to buy something when I can replenish that bitcoin at a fair price compared to the FIAT cost of the goods I'm buying. You buy the bitcoin and spend it quickly to minimise the currency risk.
