Still more than 4 millions BTC to be mined. 10% means 2,1 millions, so you are getting close enough to your plan. If you think that it will get lower price than what we have now when it is 10% remaining, then I guess you'll see the opposite price. It can be higher than what we have now when there are less btcs to be mined. You can start buying small amount of btc and holding it. We will not know whether it will get lower price again or not, so as long as you are ready to buy then just buy it.
With the mining difficulty under 3.46T and expected to go higher as the coins available to mine gets fewer each day. Then, why its market value still goes down when it reach 17k-18k few months ago? That's the reason why I still believe (cross-fingers) it will hit my target buying price. If it doesn't, I'll look forward around June or July if it gets lower than the current market value, but I won't put all my eggs in one basket. Well, like what I've said, there's still more time to think and decide, I'm not rushing myself and be attached to its current situation. I can't afford to just sit and watch my investments in a long term capacity without any results.
