The abbreviation of Altcoin is an alternativecoin which means coins other than bitcoin. The purpose of making this altcoin is to cover the weaknesses of bitcoin, namely the limited amount of bitcoin in circulation, which is only about 22 million coins, then the altcoin is made. Until now there are around 150 altcoins circulating in the market with varying prices, even there is an altcoin price that exceeds the price of the bitcoin itself in 2x, 3x, or even 10x. that's an explanation from me. may be useful
