As we hoped earlier BTC is running in a bull market now and all other coins are going down rapidly including Eth. Some guys are saying BTC value will arise more than 20000$. After Stable the BTC surely we will have a good market for altcoins. So guys what are altcoins should I buy today? Do you prefer to buy Eth or other coin lists?
Depending on your own jurisdiction yet we do have our own decisions when it comes to altcoin purchase. Always stick out for the best coins which I do only treat those coins 1-10 except for XRP

Always bought on the dip because sooner or later we cant really deny the fact that after a market price decrease there would always be a price rise. So its up to you if you can risk it up and talking about bitcoin no one knows on what price it would head up.
