There is no ceiling or floor

Bitcoin is a decentralized price which no government can control in the time of surplus or hardship, ceilling or floor is a thing that can change at anytime in the market.
Centralized price is be control by the government. Government has the power to floor everywhere with low price to purchase any commodity of your choice, also government can decide  floor the market with high price of commodity.

Who would have believed Bitcoin would rise to where it is now and in this period at that. The increase in awareness of Bitcoin and the increase in volatility experienced by crypto platforms, you'll sure to wait for more surprises.
Having no control over the activities of Bitcoin and other Altcoins has always been the issue of government with cryptocurrencies and somehow, it is a limiting factor to cryptocurrency. But then, we the absence of these ceilings and floors is what defines cryptos to a large extent and makes it remains untouchable which is the very thing that the government hates.

I see a lot of guys complaining bitcoin will never reach to ATH, it will go below $2k bla bla bla. Well, this is a message to all the newbie investors.
In a centralized system, govt can control price of a product. For instance; if price of product X increases significantly which goes beyond the hand of normal people, govt may set a price ceiling to control the price. On the other hand, if price of product X goes too low, govt can set support or price floor on a certain level.
But, in a decentralized system like Bitcoin, no one can control the price. Well, whale can manipulate but they can never ensure ceiling or floor. You should invest in BTC after learning this two point. In theory, it may hit $50k as it's a scarce commodity or even to $1000 as no one would be here thinking of having a support for the supplier aka miners.

I agree this is an open market and no experts can predict the ceiling or the floor they can just speculate on the price, when it comes to buying and selling it is to each it's own, you can buy and sell at whatever amount you amount, dumps and surge happens because of what I consider as connivance or mass action of traders to buy or sell, but no one can control the market at all times.
