I think that at the present time we can totally feel secure and invest in bitcoin. We can see the market in the early days of 2018 is going down but now has been very positive signal when bitcoin prices have increased continuously in the past days and has returned to the $ 10800 level.
This once again confirms that people gain confidence by how the market increases. Where smart money entered far below the $10,000 level, which is something they consider to be the best possible opportunity, others (not so smart money) start to feel the same right now. That's why it's quite important to have the market maintain the $10,000 level.
I believe that with the current strong buying power, the bitcoin price will likely reach $ 20,000 in the next month.
Calm down. Yes, the market is increasing, but nothing at this point justifies such levels. Don't calculate your profits already, because $10,000 is not a strong support level, where I would even like to say that at this point it isn't a support level at all. Base support levels have lost their credibility during the last correction. It hints towards a higher up movement with $11,000 as temporary peak, but it might also go down below $10,000 the next day - just let the market do what it wants to do.
