I know people that said they will get Bitcoin once it falls back to $70. They said that around $150 and they are still waiting :)
never time the market
Bitcoin's a little different. It seems to peak every 4 years when the miner rewards are halfed.
What if the current bull market goes to $200k, and then the bear market retreats to $100k? This is why trying to time the market doesn't work.
keep in mind bear market could be hovering around 100-200k after this cycle tops. tough to time the market unless you have a ton of experience in the field.
