It is very easy to say that buying eth can give us profit soon, but only few people earn because buying will only hive you profit if you have a big patience and hold, it takes years not months or weeks that is why if we don't have patience buying eth or any kinds of top altcoins in crypto cant give us profit.
That's part of profiting, being patient is worth it and it's going to be rewarding if you have been doing it rightly. There are investors that don't have patience and instead of making a profit, they all end up losing money. And that's the return that they get for being patient, there's no easy formula for one to make profit on this market but let's say that some have been lucky enough because they're able to make such for themselves and are able to do it on a short span.
