So you say bitcoin rose due to inflation in other surrencies?

What exactly do you mean by this question?

The value of currencies deflate. That means they decrease in worth and purchasing power. As a result, what is inflating are the prices of the goods and services.

If the currencies are losing value, that would mean Bitcoin becomes expensive. Or it could be the other way around, Bitcoin becomes expensive because the currency is getting weak.

As far as I know, Bitcoin's market value is not dependent to fiat currencies. The price of it is more determined by the demand and supply just like the any other things being sold to the masses, perhaps. The difference of its market value is its degree of volatility which is multiple times higher than the value of gold, as an example, as well as fiat currencies. More likely, the reason is regulation. Bitcoin is decentralized which voids the idea of regulation making its price not dependent to anything in the "world market". Feel free to correct me because that is how I understand its market value.
I don't think that is the reason why the market price of Bitcoin is having resistance at that point of this year.
This would be another case then. Since USD is being the main basis of exchange in the world market, what happens in its value might reflect to ther fiat currencies.

All these years there were numerous debate about the same topic but whereever it loses its value Bitcoin has always bounce back stronger, I don't think BTC will ever be worthless but we will see always similar debates during every dump. Since most of the people who potrays BTC in negative light are the ones who have very little knowledge about crypto.

This is undoubtedly so. Bitcoin has really surprised many positive minds who who saw bitcoin falling beyond $4,000 against predictions of $4,000 being marked as reversal price.
Bitcoin has fought easily climbing higher in this period. It has performed very well above expectation and maybe because it is the halving year, we might keep seeing high highs as the vaccine is expected, any time from the moment we can start the bull experience.

It is not possible that bitcoin lose its value, it is only a deflationary currecies, but it seems bitcoin volatility was great at the beginning but getting less volatile as more people are getting to know and using bitcoin. Only fiats are the ones losing value, especially the fiats from countries that are not developed, not bitcoin. We do not need to talked about the covid-19 pandemic crises but we can emphasize that the price of bitcoin that was lowered at a point in March 2020 that people thought the pandemic could have caused rose from $3800 to a price beyond $11000 now. I have only noticed that bitcoin price have increased during the crisis.

USDt can not lose its value against US dollar, the coin is a stable coin, also all stable coins that are like that have stable price with US dollar, they are not devalued against dollar but following dollar price trends, if dollar decrease they decrease an if dollar increase in value they also increase in value. Because of that, stable coins value against bitcoin deprecited as US dollar's value is depreciating.

Bitcoin is still valuable and not lose it's value. The demand keep on increasing that makes it valuable. Bitcoin did not rely on the value of $ but on the demand. Even their is a pandemic the current value of bitcoin is still high.  

Despite the pandemic that make so many currencies lose their
 value but bitcoin value still stand well in the areas of market. BTC was better than other cryptocurrencies which most of
them lose value during the pandemic that make some of the
supplier wonder bitcoin is still more better than fiat money which is centralized.
For my experience I think bitcoin is still well okay compare to other cryptocurrencies.

When the pandemic started there was a financial panic that lead to the strenthening of the US dollar, tanking of the stockmarket and the tanking of the cryptomarket. People were selling their assets to be able to get liquidity in the form of dollars. Then both the stockmarket and the cryptomarket bounced back hard.

So in short, the market was very volatile and not stagnant at all like you claim.
