but if you still want to invest, just stick to top alts with rock solid foundation or usage. because the usual dilemma for most new alts is that they have short lifespan or they won't even hit the exchange.
any crowdsourcing these days are not reliable. and if you try to invest on them, it is always best to dig the project before they will dig your funds to the grave.
so the chance of becoming earner is really hard to tell nowadays when we are investing in new projects.
so still better to consider investing in ranking if not popular coins at least there is a big percent of you having a safe investments and a possible profit even if sometimes will take you years before tasting the flavor but at least there is a big chances.
