The word "Alt-coin" should mean "Alternative Coins". And the word alternative in a layman's language should mean having an obvious option. Example, having an alternative plan means I can decide to use Plan B, most especially if plan A may not favour me at that time. Also, Coffee is an alternative to Tea, in this scenario, alternative is a choice and not a measure of importance. In a situation where an alternative is a choice, is therefore means that the Sorrow of one will be the pleasure of the alternative.
Relating this to cryptocurrency, if BTC who is the mother of Cryptocurrencies and who has gained extensive trust ceases to exist today, will altcoins flourish or will it make the people loose total interest in cryptocurrency.
the situation that occurs in the Altcoin market always follows the price of bitcoin in general, although there are some altcoins that make their own price changes, what I see is bitcoin which sorts all price movements up and down based on up and down charts on their own prices. Seeing this problem, Bitcoin has become the mother of all altcoins, of course the interest of crypto users if I see it is increasing.
