For those worried BTC might not go much higher. There was news circulating in social media about 80% of the total 21 million supplies have been mined and are in circulating in the market plus those are in idles. There are basically less than 5 million btc need to be mined...no need a racket science.. Supply and demand, bitcoin prices will soar high.
You should rephrase the OP because at the first place the circulating supply is not a news but it's more than a fact and I'm surprised that you just know that. So maybe if all of us know this, everyone will hold their coins as long as they could because of the anticipation. However, last bitcoin will be mine by 2140 and it's actually a long way for us and many can still happen like regulations that might affect the price.
So again, I know some are skeptical yet we should still know when to take profit. Just to be sure.
