as we know, the dollar is now rising, from the rise in the dollar it turns out that the price of Bitcoin is also rising, so what I ask here is that this is related to the dollar increase? or just coincidence?
You are right, USD and bitcoin are related. According to sources I read, Since the launch of Bitcoin, the US CPI has increased from 211 to 252, corresponding to an inflation rate of approximately 20%. Therefore, USD inflation will make Bitcoin price compare to USD by 2-3% per year.
In my opinion, the final conversion of cryptocurrency is fiat. If the USD increases, when converting from Bitcoin to USD, the value is also higher.
Its related on inflation. Inflation happen because central banks always flooding market with paper money. Bitcoin have limited supply and i think the price of bitcoin will increase so i think its not direct relation because many country consider bitcoin traded as commodity
