When the tulip bubble popped it went to $0 pretty quick. Experts had been warning this crypto stuff was all hype / BS. I don't see $0 but I see $1000 or so in a few more months. Start investing again when that happens.
The tulip mania was based on aspirational value and the price of bitcoin is based on demand supply and production value. Both are different. Whatever experts have spoken against bitcoin, are the agents of banking industry. So I prefer not to look at them.
Also I disagree when you say 1k is a good buying price! Bitcoin will never go back to that price again. So it's wise to start cost averaging by buying in small units at the current price level. If you wait for 1k, you will miss the entire opportunity.
