This is based on personal observation and studies of the altcoin market of a period of 2017/22
Altcoins are said to be the alternative cryptocurrency aside from Bitcoin and many of the altcoins are decentralized and also centralized, unlike Bitcoin which is highly decentralized and out of the control of anyone be it the developer or government Bitcoin has a total circulating supply. But Altcoin is developed by individuals e.g Vitalik Buterin Ethereum developer and teams members who are known in the society and the source codes of the coin can easily be updated which have made them not to have a static circulating which is has been the major reason why the altcoin market is hard to speculate because it circulating supply can easily be tempered more coin being minted at will which will render speculators analysis inaccurate in most cases.
Altcoins was never been easy to speculate since from the first place because this market was unpredictable even on those old years.Who are the ones who had predicted that ETH would place itself on 2nd spot in the
market? No one had really anticipated for these things to happen and this is why its really hard and even on traditional markets where currencies/indices/stocks is never been predictable.
You've been having a tug of war with buyers and sellers of course depending on what position you are.This entire market is hard to predict period.
