About countries adopting bitcoin, many countries may not make bitcoin a legal tender, but many countries will make the use of bitcoin lawful in their countries.
Bitcoin price was keep on low for now.The dump market is not a permanent one, we have to wait for the next pump.Holding is the key for the trading, most successful traders use it for the long term to get huge profit.The people who not hold before 5 years was struggling now with the money.The people who had invested and hold for 5 years was the greatest achievers now.Just holding will give you huge profit from the bitcoin.
Yes, they make a lot of money now, but they were still profitable when you invested 3 years ago because the price has doubled since then, so if we are looking for the price you also make money, but to those investors or holders who only invested a few years ago and they bought at ATH that are really not making money, but I do suggest that you are already in that situation, so it is better to keep holding, don't watch the price, just keep scrolling through social media until you saw ATH.
