i think it is, because in the year 2011 you can buy a Bitcoin for only 4$ and if you buy 100 Bitcoin before and you still have it now , then you are a millionaire , and if you buy bitcoin now it's late, because the price of BTC now is expensive
That's pretty sad that we have missed that opportunity, but no one could have predicted the future and that's only ones luck. But I have more regrets that I was in the forum at that time when ethereum ICO was conducted and I was a pretty big fool that I didn't invest in those ICO as if I would have invested in those ICO then I would have been a multi millionaire by now for sure.
