I doubt we will legitimately go as low as $100 (I'm not counting them spike shenanigans) but if we do, I got orders that will double my BTC position, and *still* leave me with a negative cost basis overall...
If we only go as low as $380 I only increase by about 5% though
We are still seeing many posts like yours - sentiment is that Bitcoin might go lower in the interim - and THAT will be a good time to buy before it goes higher. It's still a net bullish stance. We need to start seeing posts that lost faith in Bitcoin as a whole, see it as a bad investment over any horizon/strategy etc.
Of course this all depends on how much weight you give to public forum sentiment... as Bitcoin becomes more popular / mainstream this will include a greater mix of new/old/manipulators, and will hold less.
