I guess this depends on the definition of 'decent trading volume'..

ANY crypto can lose a big % within a few minutes.

It does matter a lot what coin you buy or when you are entering. Especially in short-term trading.
Decent volume alone is not enough to call an investment good or stable. The demand is a way more meaningful parameter than the trading volume.

With the current situation - where most alts are bleeding and declining in price each day - one should be very cautiously and confident regarding their altcoins invested in.
The low-quality projects will decline in short-term and never recover in long-term. While good projects will decline in short-term but eventually succeed in long-term surpassing their current value.


IMO, picking ANY coin as long as it has volume, is pure gambling.
