Are you saying its too late to start buying bitcoin? I think you are wrong because the bullish trend is just getting started, what makes people lose money in last bullrun is because of greediness, the market never crashed instantly like those pump and dump projects, it goes down bit by bit and greed people still failed to pull out what they can
I don't think it's just getting started, it could sell off anytime soon as the Chinese New Year in the European countries is approaching. As in previous years, when there were occasions to welcome the new year or Christmas, the Crypto Market was immersed in a sea of blood. So Bitcoin will only hover around $ 18k5 - $ 19k5 in the coming days, but at the end of the year there will be a strong correction. If the selling is too strong, it could send Bitcoin into downtrend again.
If you are a holder, you need to prepare yourself to these 2 scenarios. If you want to assure that you will not be losing, sell some part while you are still in positive profits. And some of your portfolio, you will be taking risk and be ready whatever may happen to btc market. You can't always get what you want, at least optimize the opportunity on hand and not end up losing huge. As no one can predict the exact things that will happen in the market, you need to safeguard your portfolio. Speculations of the so-called experts are not reliable, just follow your instincts when it comes to executing your final decision.
