1. Speculative/trading/buying coins hoping to get rich.
2. As a medium of exchange, currency to buy stuff just like you would for money.
3. As a means in itself to make money, i.e mining.
Also why did you get into bitcoin?
1. You were one of the first movers? You thought it was cool, interesting, you were here from the start?
2. Revolutionary ideas that it's going to change the world, banking system, etc.
3. You were just curious and then the more you looked into it, you saw how cool it was and promising(me).
4. Speculation, wanting to get rich.
Speculative/trading/buying is really the use of bitcoin and other cryptocurrency. It really helped me to earn more and learn new different things and it really caught my attention. Trading and buying really helped me bigtime in my expenses and it is a really good investment.
