If you waited for 2 months and now you are buying, then you still have to be careful regarding how you do it. 

Of course, if you have been buying for the last 6-12 months, you are feeling pretty smart right now, and even if you have been buying for the last two to three years, you are still feeling smart as long as you continued to buy through the whole times.

The ONLY ones who might be feeling like dummies right now are those who made lump sum buys at various points in 2021 when BTC prices were higher than now, and they are just waiting for the BTC price to return to those prices so they can get out of the red.. however those who continued to buy have brought down their average cost per BTC to quite a bit lower than what their entry price would have had been, and sure maybe some of those folks are regretting that they did not bring down their cost per BTC more by having had been more aggressive, but now it is seeming too late since the price is returning higher.. at least for those people, but at the same time, they don't really have a choice.  Each of us can ONLY decide what to do based on today, and we cannot rewind the clock to do what we should have had done at earler times.

If anyone getting into bitcoin today has an investment timeline of 4-10 years or longer, then surely those people should be getting in and getting started rather than waiting.. . and the ones who wait may also be similar to altcoin pumpers or bitcoin naysayers or no coiners or low coiners, but each of the categories of kinds of people is in a slightly different camp regarding why he is failing/refusing to sufficiently/adequately buy bitcoin... and the really scared ones might just want to start with $10 per week rather than starting with $100 per week, yet one of the problems of under-investing is that if the BTC price goes shooting up, then they could end up causing themselves regret because they had been so whimpy in their investment and they convert into FOMOing into bitcoin at higher prices because they failed/refused to sufficiently/adequately prepare for up when they should have had been (when the prices were lower.. or just on an ongoing basis for years and years and years, and then after a while they might see the benefits down the road. .but the benefits may well not end up happening in any kind of immediate timeline.. except maybe some people investing in the last 3-4 months might be feeling some immediate pay outs, and even those who started a year ago, they likely feel ongoing payouts because the price went up a lot in the last year, just short of 3x.. so far).

So some people do end up getting lucky but not necessarily realizing that they were lucky that the price went up, but sometimes they do not accumulate enough coins because sometimes they get lazy (in their BTC accumulation) when the BTC price is going up.
