This is based on personal observation and studies of the altcoin market of a period of 2017/22
But your account was just created last year, meaning is this your new account? because it is impossible that you have been in crypto market for 6 years but decided to create an account here just in 2021?
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.
Altcoin is hard to speculate know why? because they are full of shit , most of them are scammer and most have no future at all.
