You don't need to look for the uptrend, every day, pump-and-dump groups are doing that, looking for undervalued coins that is listed on a shady exchanges and then they will corner the market and claims they have 50% of all the total coins. Then they will invite others to pump it, but since they have entered much earlier when the price is too low, then can dump it easily and take the profits. That's why it's better to invest on bitcoin alone and continue to accumulate and wait for the bull run.
If you won't take the risk and stable coins is exist for you.
