Token price is not as relevant as market cap.
You can afford anything at this point.
Bitcoin could still have greater upside potential at $15 that something at 1 cent, based on fundamentals. A coin could be “cheap” based on price, but if there are hundreds of billions, you have to factor that into the relative comparison to Bitcoin, which has a limited supply of 21 million, for example.
Stellar... don’t really know. To my knowledge, it was kind of a clone of Ripple geared towards the banking system, which I didn’t care to hold onto cuz I’d rather put my support into alternative systems.
Cardano... seems like it should emerge to be a big player, though it’s also got a fair big market cap already. Might be a safe investment, though not as much upside as some other tokens with a much lower market cap with strong fundamentals that just haven’t gotten their time in the limelight yet.
Stay tuned for the next 3 parts of this series, as there’ll be a number of others included that may be worth checking out...
