Don't you think your title can be a little misleading especially for newbies who are very new to the space and eager to invest? I agree that these altcoins are created solely for profit but the thing is if you take a decent amount of time and work to understand the space then you have a very high chance of benefiting alot from it.
Such a title may seem a bit daunting, especially for entirely new people. But I think the point was to emphasise that going beyond bitcoin means taking on more risk. There are profits from altcoins, but it's a bit like gambling if you don't understand it correctly. So starting with bitcoin is probably the safest way. The rest will come gradually, with learning, understanding, and giving it time.
