Everyone hopes to get the lowest price to buy bitcoins and not to worry about the decline anymore. But the problem is if they keep waiting until the price hits bottom, they can miss buying it because we don't know when bitcoin will hit bottom. We can only keep trying to buy while hoping it is the lowest price.
That is purely the problem. Many people wish they can buy the bottom and not bother about the price anymore but the irony of the matter is that no one knows the bottom, it could be that we are right in the bottom at 18000 to 19000 dollars. Considering the all-time high of Bitcoin, it is right to say that we are at the bottom region and anyone who is serious to purchase bitcoin should at this time do it . Imagine that in few years coming bitcoin can make another all-time high to surpass $70,000. That will be massive profit for anyone that buys now.
I take it that anyone speculating further to buy at any other bottom is not serious to get bitcoin, either you by now at once or you by using dollar cost averaging at intervals.
So buying at the current price and keeping it for a long time can give us big profits in the future. Unfortunately, people don't realize this and keep hoping to buy at the lowest price and keep waiting. We can only give them suggestions that might be useful but the rest is up to them.
