Is the OTC market good for trading?

OTC market investment is speculative and involves a high degree of risk. Most securities are thinly traded, illiquid, and experience increased price volatility.

It's difficult for investors to trade on the OTC market without dramatically affecting the quoted price.

Like any other stocks, Penny stocks or OTC trading can be profitable if you take the right approaches. But penny stocks usually come with a high risk, so if you are not willing to take high risk then it is better to avoid it. Penny stock is extremely unpredictable because the stock could go up by a big margin, while it could also drop significantly in a short period.
