In this time it is the time to buy altcoin and bitcoin because there is a massive price decline and again the coin in the top ten may be the right choice for us to save so we don't always fall and go back to the moon again
The most important issue of altcoin is the large number of coins that do not experience an increase in the crypto exchange, so the price remains cheap, because of the mistrust of the merchants against the coin.
Maybe someday there will be natural selection where there are only five tens of coins or even less who can continue to trade because they are liked by traders. Without a continuous trade, the coin will die automatically, if it does not die the price is very cheap.
