It wasn't 12k in a decade ago. It was 12 USD. Probably a typo or you read it wrong. But yeah, those you held for a decade (I wonder how many of them are there), invested a good amount is probably leading the life now. But I doubt we will be seeing the price go up the similar way in the next few years or in a decade.
No matter the price of bitcoin, if you have money lying around, you have been given a second chance to invest. Every moment is a second chance!
The difference isn't 7k USD. Look at the picture he posted. Now would be saying the same that gold has been performing better than bitcoin in the long run?

Some says HODL isn't that easy people can thinking it as. You can see your portfolio climbing up easily, enjoy the ride but one can't HODL when the price gets down, specially in a capitulation moment. However, imagine you had 10000 BTC purchased with $100k @$10/each. When you would see your portfolio have turned into a billion and again it got down to half billion, would be still able to HODL? I doubt many would but brave can and that's where they have the advantage to be the billionaire.

Sometimes I wish I knew about Bitcoin earlier. Early adopters of Bitcoin had a once in a lifetime opportunity by being in the scene so early. I learned about cryptocurrencies somewhere in 2014, which isn't too late I guess, but being a moneyless teenager, I couldn't do much to acquire Bitcoin early on. I remember asking my parents' permission to use their card in order to buy one whole Bitcoin but getting rejected. Thus, I resorted to trying to acquire BTC in other ways, such as faucets. I managed to accumulate a decent sum through them, but it wasn't any life-changing amount, even by today's standards.

For those saying that Bitcoin's price is irrelevant, it's not. We don't share the same opportunities compared to the past. A thousand dollars could get you a couple of BTC in 2013-2014. You'd only receive approximately 0.05 BTC. The possibilities of multiplying that kind of money now are way too slim compared to 2012-2014.

We will not get this type of increase ever again. From 12.5 dollars to nearly 20k dollars, that means it has increased 1600x times bigger, in order for us to go x1600 bigger from the current price, we would need to be 32 million dollars per bitcoin.

I am not saying that it won't go up, it will go up and make you rich and you should invest into it, but do not imagine for a second that there are a lot of profits to be made left. You could make 5x, and that's more than good enough in this market and we need to prepare ourselves for something like that. If you get ready for 1600x then you will be sad, but if you get ready for 5x then you will be ready.

I understand your point, but we'll never know still. What if we will dump at a huge significant price of Bitcoin then it will go bounce back on some high price?
We all know where Bitcoin will go, the same as what happened years ago when Bitcoin are starting. Or maybe if ever we will get on these high prices, for sure we don't exist anymore in this world.

It's everyone's wish, but I suppose even if we had enough knowledge about it, we wouldn't have bought it at the time. We want to go back to that time because we already know what can be achieved today, not because we have full knowledge of it and want to possess it because of that knowledge. Those who made the first bitcoin transaction or those involved in bitcoin development at that time they had a very good knowledge of bitcoin but who will hold bitcoin until now?, I think definitely not. Even satoshi was skeptical of its development, no one was sure at the time.

really it's time for us to invest by buying bitcoin I'm sure bitcoin will go to another month like 2020. I hope we can all feel something like that again.

You said what I was going to say. I do agree that the days of exponential growth counting from ATH to ATH can no longer happen. Getting in November 3.5x from 2017's mark only confirmed that.

But who's to say Bitcoin won't experience an incredible dump, as you say, even below March 2020's bottom?

I personally think that in the real of highly unlikely but Bitcoin's about to experience its first global depression.

$4k? $2k? Then another 20x from there to next ATH isn't just possible, it's probable.

I don't know why you think gold is performing better than bitcoin, but when you look at the growth of bitcoin compared to gold you'll realize what you're saying is untrue.

Networth of bitcoin 19K$/Bitcoin Is much more when you take into consideration all time gold value and compare it with bitcoin's all time value.
