I'm glad that I was able to buy more BTC and keep selling it again when it went up, which is a rule that isn't just bitcoin, but almost every financial market is.
Just keep this in mind, nothing will increase forever and nothing will decrease forever.
everything in trading can be sure there will be times for ups and downs, so I agree with you that nothing will increase continuously and also fall continuously, there is always dynamics.
we buy when the price drops and sell when we are sure that we have met what we want and that we have increased sufficiently. and it is a certain and natural thing for all to do.
Happy you are if you have bought a lot of bitcoins when the price was down and now with a high value is worth selling. then the benefits you get are very happy.
