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.
Altcoin is not a bitcoin.Whenever their is dump in bitcoin price.All the time, the price of bitcoin reduced, the price of altcoin was reduced a huge value. The recover of the altcoin price is not easy one. Once it reduced 10 times, it will recovered for 4 times. When again bitcoin price reduced, it will further reduced to the bottom of cup.The only way to recover full lose is, you need to inverse on best altcoin. Secondly you should wait for the longer time.
