How exactly do altcoins gain value? There are so many altcoins out there and honestly you can see connection among these in terms of the drop and rise of price.
The reason of drop and rise in value of alts along with rise and drop in bitcoin is due to the fact that the price of bitcoin reflects the average sentiment in the crypto space. Most people including me invest in alts to increase my bitcoins. Remember almost 90% of the coins will cease to exist in the future, but bitcoin is here to stay!
