Never. We are not in bubble territory, we are were we should have been naturally if the Willybot Mtbox incident didn't happen. You could call it a buble if tomorro we wake up at $5,000 or something. The price keeps growing in a healthy way, with small dips there and here.
If the ETF passes, due psychological factor associated with the ETF = big pump, it may dip, but I don't predict sub $1,000 prices.
If you sell before ETF: you risk that you miss on massive gains if it gets approved.
If you buy before ETF: you risk that you lose on the gains you could make if it doesn't get approved since you could buy for cheaper
It's a gamble.
Granted, the price has grown steadily in aggregate if you look at the last 5 years. This is good for bitcoin.
I'm worried about the developments in these past 3 months: Its more than just the ETF. Why go through a third party like the twins to get shares in btc when its so easy to get the real thing yourself.
