as we know that there are too many coins in circulation.
What do you think of choosing a good coin to be used as an investment?
It depends on the risk level that you are willing to take. Relatively low risk - buy Bitcoin (maybe already now). Seems BTC is near the bottom. Though level of 2200-2500$ nobody cancel.
For moderate risk it could be LTC or ETH for example. And for high risk it could be one of hundreds low cap alts
