It is best to buy bitcoin when the price is low, but the bitcoin price goes up everyday, so i suggest to buy now because its i believe it will never goes back to its previous price.
The problem anyway is still subjected to the fact that we do not know the low point yet as bitcoin has a way of ultimately surprising everyone. Like you said, buying now is still pretty perfect, whether it goes back to the previous price or not. I missed buying at $5700 because I was hoping for dip and then I missed buying at $6000 again cause I was still waiting and here I am now still waiting
and that is what happens when you miss the right moment and end up buying higher eventually.
There is no time to buy Bitcoin, if you buy Bitcoin while the price is still low, you are lucky. If you buy Bitcoin while there is a price drop, you are lucky. But we never know and can never predict when the price of Bitcoin will go down, rather than wait for an uncertain time we better buy and collect Bitcoin as much as we can. If you keep waiting, Bitcoin prices will continue to rise as time passes. Do not ever wait to buy or have a Bitcoin, you'll just lose it. The sooner you have Bitcoin, the sooner you get a profit from Bitcoin.
Yes, it's good to buy when the price is found to be low. This will let us get profited when the price increases in a short or later. Bitcoin is all about the trust, because each and everything takes place in a virtual manner without any form of physical appearance. User who has sold high around the price of $17500 could now make it an opportunity and can buy once again expecting profit at the earliest through increase in price.
