But bitcoin have droped almost 20% in this month
Since they exchange immediately for fiat, it doesn't scare them that much..
The more stable btc value will be the more people are going to spend em instead of keeping em hoping they will increase in value. Stabilized value will actually be good for widespread adoption.
True, but I don;t think it will fully stabilise for a very long time. You might have periods where it seems quite stable, but will then surge or plummet depending on some news.
