The market at present tremble to move on the bullish side. If the $40000 tag gains resistance then it'll move forward reaching $50k in a short time period. The price found below $40000 is a good sign to invest. By the falling week if it hasn't touched $45000 then for some time period we can expect the price changes to happen same as that happened around $30k to $33k a week ago.
I agree with your opinion, if the price drops below $40,000 it's a good price to invest. where we can see previously that there was information about discussions last week between Jack Dorsey (CEO of Twitter), Elon Musk (CEO of Tesla), and Cathie Wood (CEO of Ark Invest) at the Bitcoin conference.
They talk about where they see Bitcoin and cryptocurrencies going with regards to their own organization. This shows that bitcoin will fly up in the future.
