Mr kevinzxz you have answered correctly, there is no better time to invest into bitcoin or other crypto than now. The best decision a newbie can take in his crypto journey is to get into accumulation as soon as possible, even if you'll not be able to purchase a full coin, with the help of DCA it will be possible. Just like the example you cited, in 2018 we experienced a drastic decrease in price but today, the current price is better and so will price also appreciate in the coming years also. For Bitcoin I am sure the price will continue to increase due to the idea of only 21million coins in supply. As adoption increases with limited supply, this will bring about scarcity and from the law of demand and supply, when there is scarcity with increase in demand or the demand remains constant, there will be an increase in price. I believe Bitcoin or the crypto system is not an exception to this theory, so let invest now and see our portfolio grow.
