I want to earn more money for a better future.
if you want to plan finances in the future, at least Bitcoin can answer those needs. driven by the growth of Eth will give you a little idea of how both could benefit in the future.
but apart from these two potential coins, you have quite a lot of time, to research various other altcoins where at least they grew out of a large community.
keep using CMC rank 10 for research.
that way for quite a long time you will not only depend on Bitcoin and Eth. maybe another altcoin can provide potential that at least won't make you regret investing in it.
always to make CMC, as a reference if you want to determine altcoins that might be used as investments in the future. it's true what the colleague said above with a little analysis that can be done if we can determine what coin we will invest in by looking at the top rankings in CMC.
if bitcoin and ethereum are clearly very dominant to be used as the first benchmark for investment, but in terms of price of course the capital prepared is also not small if we still want to invest in bitcoin and ethereum. but for future investments, there is no need to doubt the two.
but there is nothing wrong if you also want to take a moment to pay attention to altcoins that are just growing on the market or being marketed. because now many are good enough to be used as investments because they can also play a role and there are advantages when buying it is clearly cheaper and there is a bonus of its own.
