Sure they will definitely regret not buying when the price of bitcoin was below $100k because they missed the chance of buying at a lower price but it's not even late for them to get started if they have their discretionary income ready since Bitcoin is just growing in other not to further regret I believe in future that the current price now will be considered as low compared to what it will be in the future so their is opportunity to get started and start accumulating Bitcoin gradually by adopting the DCA strategy and gradually grow your Bitcoin portfolio.
Some people are already complaining that bitcoin price is already too high, and they can’t risk their money in bitcoin right now, some of them do say if bitcoin price will increase, they won’t really be getting much profit because the price is already high, and I will say thats the reason why most people do invest in altcoins right now, but they are completely wrong, bitcoin price is not so high yet, and everyone can still invest in bitcoin. If you are investing in bitcoin, then you are definitely going to be having peace of mind also. People won’t regret not investing in bitcoin right now, but they definitely going to be doing that later in the future, and their regret won’t be bringing back the past.
Guys who complain will not find any valid argument to criticize them. Even when the price of Bitcoin was $45k, they expressed opinion and tried to mislead investors. Similarly when the price will be $150k or more due to the pumping effect, they will criticize the same. In fact the price of Bitcoin is still passing the initial stage and the states are still preparing to increase the strategic reserve. Corporate holders have continued to buy more, started Bitcoin for global intra-trade transactions and are preparing how to further expand its scope. It is logical for investors to continue to accumulation in every possible impact and expansion of Bitcoin in a long-term DCA strategy.
