Bitcoin's price rally is based from:
1. The normal bitcoin price chart.
2. Some manipulations from the big whales.
3. Price adjustments vs Alts.
During price rally, I usually sell all my Alts to BTC, because alts tend to dump for more than 40%. So what I did is to buy it from the bottom.
i'm new to the bitcoin community so i'm just very curious about what causes the prices to sometimes skyrocket but then drop really low so quickly. Thanks
