I now have $ 500 in capital. Is this the right time to hold the coin. and what kind of coin should I hold? I need some advice now, Because according to my judgment this will be the momentum for altcoin to explode in the end of 2018
Sometime you need to sell the coin when the market is bad if you want to buy more good coins in this cheap price.
If you have $500, you can start to buy more without afraid of your coin value never going up.
Last year, all cryptocurrency reached their peak, i believe it will be occurred again someday.
