Don't you worry because I believe that he is not referring to Polygon when he said that, according to the next sentence that he gave out specifically or especially when he said the word ''persistent''. For me, I think Polygon is not exempted and even BTC which is known to be the king, still have some downtimes too. It's only normal but what matters the most is if they can bounce back again and become more stronger next time. Both coins already proved it anyways. You said you only invest a little in BTC but I think you are mostly into alts because it looks like you already have 3 solid alts before Polygon.
I think there is no problem with that but it is only if we prioritize the crap alts and the low-quality ones. We can't just stop the people from trading using Polygon because cryptos are not only limited to investing but they have plenty of use cases.
That is true, there aren't really any investments in the crypto world that has zero risks, we have so much risk at all times and I believe that we are going to end up with a good result without much issues. This is why I believe that people who are worried about this one, should be worried about another one as well, it's just not that clear to do anything without understanding what the others are doing as well. To make a prediction about crypto you have to understand about the market in general and not just one of them at all.
This should be something that will take a while, and because of that I believe that we are going to make some returns if we trust the market along with it. For example, you can't make a prediction about polygon, without making a prediction about the market because you need to do both to get the answer and can't do just one of them. This means that if we trust the market to go up then we are going to trust polygon to go up as well.
