Yes you are right, it's very hard to predict but if I may, I would guess around 35K USD. Bitcoin will definitely going to grow more compare to what it is today. So Lets hope that by the end of 2018,  its going to be crazy in crypto world.

Bitcoin for sure will go up and down but I don't think it will come to a point that it will lose it's value. The world's current requirement now is very digital already and bitcoin or Alts is the answer on it.

Income - Less Savings = do whatever your want. Kidding aside, pay yourself first, that's the best way to save money. Then put it somewhere that you can't easily withdrawn. Keep it away from your. Then don't spend on things that is not necessary. In no time, you will have a very good savings.

I'm new in this area and I'm sure once I do my due diligence and work well, I'll be part of the new rich created by bitcoin or other Altcoin. Congrats to the new rich who manage it through the storm in bitcoin. You guys rocks.

I'm sure time will come that renewable energy is the main source our planet will use. Oil became very toxic in our earth. I guess it bound to be in the bottom of the earth only as it has it's purpose their. But currently, we don't have much choice. Hopefully Government will be able to really gear up into using renewable energy rather than the fossil fuel.

The possibility of bitcoin to reach 50000 USD is possible. Bitcoin has a small token supply, there the value of each coin will really going to increase base on the current demand. So it's very possible. Let just wait and see.
