If you want to buy dips and take some profit on upward movements you need something you will be buying
with.
Just yesterday or so at
https://www.bitmart.com/trade/en-US?layout=pro&theme=dark&symbol=DMD_BTC a good example happened of why it is very important to have your buy offers already in place
before a dip or dump happens; I stupidly had not had my buy offers column more than just barely started building downward before that dump happened, as I had only just brought some DMD back onto the exchange and not much of it had sold yet so I had not yet gotten much proceeds of sells with which to build my buy-side.
I went to watch a couple or few episodes of a TV show and came back to keyboard to find that not only had a deep deep dump/dip happened but already the price had recovered massively from the bottom that had been hit.
Thus my failure to have already had buy offers in place all the way down at least as deep as that dip/dump penetrated caused me to miss out on the extreme-bargains pricerange of that dip or dump.
So if you are hoping or planning to buy dips, be aware that the most-delicious ones can easily be mostly over before you even become aware they have happened, thus that it is important to be in place with your buy offers ahead of time so it is your offers the dumpers or dippers are dipping or dumping onto.
Similar applies the other way up to skyrockets. Typically with a real skyrocket the price almopst instantly jumps back down half the range it jumped, so again you miss the best part of it if you don't have sell offers already up there waiting for it.
Hence the strategy of building columns of offers "all the way" down and up from the "spread".
This has historically made such a massive difference that the much-mentioned dangers of leaving stuff on exchanges turned out to be just a cost of doing business, a dent in profits, rather than any kind of serious loss, at least once one has managed to diversify off of one's first exchange and especially once one is on a few, and over the more than a decade gone by it has even seemed like the percent of exchanges, or at least the percent of those one might actually consider giving a try, that turn out to be created from the outset with a plan of using "oops we got hacked" as an exit-plan even seems to have gone down somewhat.
(Or is that impression merely from me maybe being a bit more conservative when considering exchanges? Hmm.)
All this means that ultimately it seems better to be buying with an altcoin than with fiat, since over the more than a decade already of doing this fiat has surely gone down in value, so had I been trading against fiat rather than against altcoins I am pretty darn sure I would have had a whole bunch of built-in loss simply from choosing such a shitcoin; fiat is for sure long term a shitcoin, in theory some other alts might not be, or certainly not as shitty as fiat.
Also, if one is actually successful, surely in the long run it ought to be expected that one would be earning, and buying fiat with, crypto rather than earning, and buying crypto with, fiat?
Unless you somehow expect your fiat earnings to keep up with or exceed your crypto earnings long term???
