if seen from now its time to buy and hold altcoin. because the current crypto stock market is declining, including bitcoin. but it is only temporarily mid-2018 that there will be an increase again against altcoin and bitcoin.

where the dev of coins and investors keep market price stability later. let alone bitcoin will be a lot of events that will take place. and altcoin such as ETH, NEO, XRP etc. Such coins will increase as well.

I've bought altcoin and hold like NXT, XRP, and ETH
