Don't get lulled into a false impression of equivalencies between cryptos, merely because we have short term simularities (supposed synchronization) in performance - that happens sometimes, yet it does not necessarily play out on a longer scaler or even speak to some fundamental differences between them.
There seems to be one guarantee though, all crypto keeps rising in USD price regardless of bubbles and busts
Is this correct?
Sure all cryptos have been in a considerable price appreciation in regards to the dollar for nearly a year now, and sure, such ongoing crypto pumping can occur for another year or two (surely not guaranteed), but even if various cryptos are pumping simultaneously, that does not take a way from the fact that some of them are pure crap and they are just caught up in the pump.. so merely because they happen to be top 10 in crypto, does not necessarily make them good or good investments in relation to bitcoin, for example.
Also, we know that sometimes, you can make way more in various alt currency pump and dumps (maybe even 10x more than BTC or even greater), but those kinds of historical facts do not make those alt cryptos equivalent to bitcoin in fundamental terms - even though they surely are likely to be riding on bitcoin's coat-tails of success and security in order to achieve their own level of price appreciation that might dwarf bitcoin for short periods of time and even allow people to become rich faster, if they can play their cards right and not get scammed in such pump and dumps.
Anyhow, the recent consistent and ongoing superior price appreciation of various cryptos in regards to the dollar does not guarantee in any way that it is going to continue or even continue consistently when some of the scams are discovered, which could also take a considerable amount of time to realize that a large number of the cryptos are scams or at least they do not have fundamental value beyond theoretical and beyond a bunch of folks pumping money into them.
