The demand can be affected by the world economical situation, but it doesn't fully depend on it. The demand can be affected by many factors, even manipulation can trigger the rise in the demand. But mostly the demand is affected by the news and the trend in crypto market. If crypto has a lot of good news, the demand probably increase since many investors believe in crypto future. Another reason, when crypto market seems to start a bullish season, the demand must increase massively. I think these factors have a bigger role than the world economical situation.
