Bitcoin has its own advantages and disadvantages. As you have mentioned, it is quite easy to trade with Bitcoins and to convert them to fiat money. At the same time, there are disadvantages as well, such as the high probability of coins getting stolen. Let's wait for a few more years, and see whether BTC can rise up to our expectations or not.
Yes you are right with that, but for me, if you are comfortable using and having transactions with bitcoin, then continue using it, or if you are
comfortable using trades with gold then continue it. But we can't deny the good future awaits for bitcoin as the signs of it's price is happening today.
Expect for the best for it.
