If you have a long term investment plan e.g., 4 years or more - and if you don't plan to sell whatever happens - then short term movements shouldn't matter to you too much. Adoption seems to be increasing, and in three years there will be another 'halvening' event which I would expect to give a nice price boost then.

If your aim is long term investing and you don't want to trade, however, i would suggest using the 'dollar cost averaging' method which just means: buy a regular additional amount at regular intervals, e.g. Every week or every month. And, in fact with this method, a price drop is not actually a bad thing because you get to buy some of your stake at low prices!

Caveat: there are however some key principles that are good to follow if you invest in bitcoin: Don't ever invest more than you afford to lose, and be prepared to accept that bitcoin could fall to a very low value even if that may seem unlikely right now, because it isn't backed by any government or tangible good; it's only backed by how many people use it to transact and for a store a value.

understood many things thanks for helping me out and yes you are right it better to buy in regular periods
