Do not regret your decision, according to what I can read it seems several of your friends were scammed while only one of them became successful, as such it is likely that instead of being one of the winners you would have lost your money to scammers and you will be in a difficult situation now, so instead of thinking of the missed opportunities think of it as if you were not ready at the time to invest in bitcoin, which you were not, and think of your involvement on this market now not as coming late to it but as the moment you decided to bring a positive change to your life.

Regrets won't mean anything if you won't act through it. It is okay to have regrets because it simply means you have realized something from it. You did not invest in the past for a reason; more likely you can't afford to lose money at that time and that's a valid reason to not do so. You'd end up in huge loss right now if you have invested without being mentally, emotionally, and financially prepared given that the market is just too volatile for fragile investors. Now that you have come to that realization, you can now make a decision whether to shoot your shot at the present or regret again in the future.  It will never be too late to start something as long as its progress is continuous as well.

You still have your second chance if you are seriously looking for another chance.

In January 2018, Bitcoin was traded under $20,000 or about $15,000 in middle of 2018 January. Depends on when you used to compare to now, if it is December 2017, Bitcoin got its all time high in that year around $20,000 and you can use two prices, $20,000 and $15,000 to compare with Bitcoin price today that is a little higher than $30,000.

If you look at two comparisons, today Bitcoin only x2 from its price in 2018 January or even less, about 50%+ from its price in December 2017.

Did you miss any chance? Yes.
Do you still have another chance? Yes.

They were scammed because they did not invest in Bitcoin but chose altcoins.

Once again welcome to bitcointalk platform.

Good to know that you have learned something from your past and you have accepted how you could have been on a different path of Bitcoin possession if you would have taken the chance. Most of the peeps on the forum have the same story. Most of them also developed a sense that it's never too late when you are in the Bitcoin. You can always get started at any point since Bitcoin's movement or future is strongly associated with exponential growth. Well nobody needs to prove that also since we are seeing the trading view from the beginning and with some ups and downs bitcoin has kept its course towards high rise prices all the time. For a person like you who now understands bitcoin and time relationships, you should start the journey from this point onwards and be a good example of the best holder ever. Good luck with your future endeavors with bitcoin.

Of the many suggestions that we hear from friends, even if it's only limited to ordinary discussions, it can become material for study for us when we have moved from that place to rethink all the discussions earlier. Usually there are one or two things that can be useful if we do it.

It's not too late to do what you think has lost many opportunities in the past.
Simply put, take valuable lessons from the Bitcoin birth process.
In the past, quite a lot of people were pessimistic about the idea initiated by the creators of Bitcoin.
This forum is open to people who want to learn and are willing to share information about Bitcoin in many spaces.

Undoubtedly, this platform serves as the quintessential hub for us to glimpse into the future of Bitcoin. Consider it our primary abode, where all of us who support Bitcoin can flourish alongside civilization. I affirm that this forum exerts a tremendous influence on the advancement of Bitcoin and remains at the cutting edge.

Therefore, let your past regrets be an isolated occurrence, never to be repeated again, for you have discovered a haven where knowledge is generously shared, free of charge, through the written word on this forum. As I continue to educate myself on Bitcoin and cryptocurrency, I implore you not to allow yourself to fall behind others.

Those who have the power to hold, will not only just hold it but would have also bought it in phases whenever it crashed down. They're smarter than the ones who just hold alone and do nothing. Because the risk you take from the downside is worth the investment because you not just try to earn more through your profits but if you wish to take out your money early with less or no profits from the positions taken from its high, then you can go for breakeven and I guess many had the chance to do that. However, welcome to the forum. I hope we will all be very useful to you in terms of providing the kind of help you need and we expect that you too become one of the greatest contributors of this forum.

Lol what? Negative impressions?
Dude, I believe you're new to trading or something?
Even small traders can diversify their money and keep it for future purchases where they can buy more for less whenever such situations like a crash arises. Lol tell me if your small trader have gone all in at $69k and sold at $16k, what would he make? A huge loss. But if he'd have bought at high for some % (let's say 25-30% because we all know that we are surely going to see a top and it's definitely going to retrace) and then decide a level like $45k and then the final purchase would be at $25k (assumptions I'm talking about), then he'd still be in some profit that'd cut his losses a little. But buying with total capital is stupid and shouldn't be done, you must have heard - never put all your eggs in one basket. I'd say that put your eggs in that basket one by one at different times and different areas and you'll be fine. Don't get offended by my words but as I understand, those who come here and think that Bitcoin is a get rich quick scheme and invest, they'll surely lose because of their mindset.
