if I start trading with a little money I will buy a high volume coin and the price is still low, because at times like this we will be able to profit when the price starts to rise, I do that because it reduces the risk in trading.
Mostly there is an accumulation on those coins , thats why you see the volume high but the price is not moving because buy orders or too much and those coins can give high ROI on the long term but you must be patient and also it could take months for them to move , so the best is not to invest much money in them if you are a day trader , but for the long term definitely they are the best choice so far .
