Bitcoin can die when it reach limited supply. There is no more profit for miners and even if they increased Fee, a lot of users will decrease. Bitcoin is just for currency and if no one use, it is fail.

Investing for the future is always the best move but in my opinion, saving 1 bitcoin for your retirement plan is too risky since the price of bitcoins are very inconsistent.

Bitcoin is very easy to get, besides coin in the internet that has the highest value is bitcoin, so I really like bitcoin of the coin the other.

I am planning to gather as more bitcoin as I can before it gets to $10 000. This year i guess bitcoin can go up to $3000 and in a few years it will worth a lot more.

The best thing is to try before make a decision. For example, you can trade with small amounts and see how it works and if you are good in that.
