ultracoin is rising. and btc will be $800 within 2 weeks

Don't be in such a hurry son.
We could still be in turbulences for the next 2-3 months, so HOLD and don't despair.
When you put money on a savings account you typically do no longer care for a number of years.
Try to get this mentality with UTC and you'll most likely be rewarded.

Seriously how do you know stuff about btc price in the next weeks let alone months?

I thought you were guessing based on inside info, but now you apparently can predict the next drop, then reprise, then re-drop etc etc.

Wtf?

I don't pretend I am right, so read the disclaimer in my previous posts. My decisions are based on my experience as well as opinions of trusted people around. We happen to be right on average, but mind you: we can always be wrong, so do not think whatever I say is a winning gamble.
Observe the situation, try to feel the market, and then take positions, but all in good faith and using your best judgement.

Do never forget that getting rich quick is unlikely to happen.

Holding, on the other hand, is probably the best strategy in crypto as can be seen over the past 2 years.
