We see many scam ICO bounties in the forum. But there is no way to understand what is Scam, which is not Scam. Is it possible to catch anything by following it? 

At the beginning of the year we saw the price of Bitcoin dropped to 50%+ and above. But in the last 7 days, I saw it increased by 20%+. Its realy good for bitcoin Holder. Bitcoin prices can go back to the previous position?  
If can go, how much time it can take?

I have 100 Waves. Its price now falling down and down. I'm in Confusions Sell it or Hodl it now!
