If you've got the funds to buy a Wholecoin, awesome but if not, you could buy in sats and HODL and still make your profits.
Right now, every sats is important when people are looking for Bitcoin to hit $1 million; for the majority of us, it is hard to obtain one Bitcoin, but that does not mean that we should look for other coins to HODL and make a profit we can do DCA a $50 worth of Bitcoin every week, that is going to worth a lot in few a years, so we should not delay accumulating sats however small.
Indeed, every Sat counts, whether you're a large scale investor or a small scale.
Sometimes it's even more effective and profitable to invest bitcoin by bit on a regular interval, even when you have the money to lump sum, except of course you're currently buying a DIP, but if it's a bear market, or even in the middle of a bull market, tye DCA strategy can be a lot more effective because it'll give you the advantage of buying at different price points, you can even buy more when the price is lower and less when the price high.
Let's assume you have $50k to invest in Bitcoin, and the market is currently on a bearish trend, rather investing all 50k, you split the money and go on a weekly $500 DCA strategy, and you'll see that, by the time you finish investing all 50k, you'll be having more than 50k in your portfolio, except there's a DIP in the market.
