Just do not panic my friend because altcoins is just like bitcoins they are volatile which means the value of them are not stable. They will always goes up and down like a roller coaster ride. Panicking is not a good way to be better in this business. Not unless your altcoins are just another shitcoins but lets hope that it is not because if your altcoins are those top altcoins like ethereum litecoins and many more that is normal for them to go up and down in the market and a lot of people are saying theybare going great this time so no need to worry.
