People suggest those coins because of their experience. It's free advice and you have the choice to accept it not. I have been watching the market for all these years and feel that small cap altcoins are not worth the long term only some short term gains may be possible if the coin goes up which is again 50-50 chance. You might have something better to say than the older members of this forum having a bias towards bitcoin and you are free to voice it but do follow up your advice yourself on paper.
My choices are always bitcoin, ether not altcoins in the bear run to sell on the next bull run.
And that short term trade is not even 50-50% chance as well, there is a 1-99% chance because we are talking about so many coins and tokens that will end up being terrible, people should be aware of them. I believe that we need to reach to a point where we could make some decent money, and for that to happen we need to pick something decent as well.
Picking a low cap coin to make a profit means that we are preferring something that is lowly and that is not going to be easy for us at all. I believe that we need to reach to a point where we could make some profit, and it is not that much possible. I hope that it gets to a point where we could make it work, and for that to work we need to end up having some profits for sure.
Its a digital maze, and it looks like you'd have to look through a lot of things to find the jackpot with low-cap coins. But keep in mind that each coin has a history, a science, and a team behind it. Studying is very important.
Reading white papers, getting to know project goals, and evaluating teams can help you make a smart choice instead of a rash one. Choosing the next "big thing" isnt easy, but a good guess is always better than a hopeless prayer. I agree that making money is the goal, but lets put information first, because that will lead to making money in the end.
