Let's just say you woke up one morning and you noticed that something odd is up with BTC and you look closer only to realise that BTC is down to 1$ meaning it's dead to many, would you still decide to buy some or you will exit crypto space instantly
You know what? I have dreamed about such an occurrence more than once!
If ever BTC touches below $100, I will sell every asset I have, and I mean, everything! and will buy BTC for that. That said, whenever and if ever this happens, I will also check the reason why a drop like that happened in the first place.
The most probable reason would be that a technical fault was found in BTC and in that case, even I will hesitate to buy more. Given the kind of robustness we have seen in the mechanism though, I don't think this would ever happen.
If it happened because a massive hack happened or someone crashed the market or anything like that, I will stay true to my words and buy as many BTC as I possibly can.
