I mean, the best time to buy bitcoin primarily depends on the situation of the market. That is why there is no universal standard of a "cheap" price of bitcoin in the market. But you will base everything on the recent data, market volume, and history of prices in order to deduce when was the last cheapest price of bitcoin.

Just to give you an actual example, 2-3 weeks ago the price of each bitcoin was sitting around $5,000-$5,400. Currently, the price is at $5,900 with at least a +$500 on its price. So if you purchased bitcoin back then you would be able to garner profit in this specific time frame.

Many people have been asking about the right time to purchase bitcoin for investment. I say, the best time is when you have decided to purchase at that current time- which is NOW and TODAY. If you are aiming for short-term income, then today may be the best day to purchase. If you are the HODL type, then today also may be an opportunity!
