This time the market condition is going to down trend day by day by some time and bitcoin and altcoin signal providers are almost unfavorable to trade because bitcoin and altcoins are going down and thats why the main thing is where to invest and when to invest by following market condition is the best way instead of using signals providers strategy, I think this time is best to both bitcoin and altcoins according to market situation and the best trade is picking from depth and sell it on high price and dont save for holding if you are doing daily trading but if you wants to long term trading on altcoin and bitcoin then it good to trade in good coins,
