This is arguably irrational market response - supply of new flavours of coin, some of which may have been just 'me too' opportunistic issues have been stopped. Coin already in existence has less competition for investment/speculation........ so prices dump?!?!....... I'm adding at better prices..... crazy crypto world.
ps. and sound money (Gold /Silver) have been volatile so as you say Stacy, a good training ground for crypto-land
