that much in such a small period. If you look at the last years he didn't rises allot so don't be to happy about it.
it's not reasonable i think stable at $5000 is enough
Damn you know 2020 isnt that far away right lol.
So to think anything near 5k seems absurd, and that would mean its a easy $10k for someone hold 2 btc.
But you must also to take some risks with Bitcoin otherwise it will be not possible to make any profit.
If you take it as a problem then you are really a newbie in market. If you just take your time to learn something about how the market moves even in other currency as well, you will realized that price fluctuations is not a major problem. Others make profit out of price fluctuations. If all will know what will happen in the future about bitcoin price then definitely we can't make profit.
