Almost everyone is wrong, and only because; Bitcoin is not at all about all the deep dips but the stabile growth with the high peaks. That's it and that's all of what most of them just don't get.
Everyone is really overexaggerating I would say. There were huge dips in the past and we can't really deny that, people are free to say it like that because it was real and true. Those huge dips were a great opportunity for us to grab some bags with cheap price and then you had a chance to get a bigger profit when it's the right time in the future. There will be always some of those in the future as well, you can't avoid that.
Buying at a very affordable price is one of the ways we can earn from the market without over exaggerating about making more profit from the market when one buy at the price of 71k. This is not a fair price to biluy Bitcoin because the price is up already.
If one bought at the price of 40k or 50k, I think that is still fair and profit can be easily made. We need to measure the price and think what we expected to get from the market. If the price of Bitcoin finally reach 100k, the person that bought at the price of 40k would be in more profits especially when the quantity is large enough to earn more from the market.
