Not only is the price of the bitcoins increasing, but also the complexity of their mining. It is much safer to invest in bitcoin, it will still grow in value in the near future. I have contracts in cloud services, for today they are all unprofitable.
Can't fully agree with you.
Let's imagine the future: you invest now 6k$ in 1 BTC and hold that till it's become worth 100k$, lets imagine that in 1 year period, what means after 1 year you will have the same 1 BTC.
And another option: you invest the same amount of money in mining powers, so in 1 year period your 1 BTC will turn into 1,2 BTC (120k$).
It's just up to you to decide which option is more suitable for you.
