I won't buy ADA, MATIC, XRP
It is your right to stop buying any altcoin. But you should enclose valid reasons at least. I agree that XRP looks quite risky to invest because they have some bad issues. But I don't see bad issues for MATIC and ADA. Even these altcoins have showed good progress lately, they also have some good news. MATIC and ADA are also 2 top altcoins with strong fundamentals and they have big community to support them. So, why we shouldn't buy them, dude?
That was a straight answer but I could agree with that because of my previous experience with ADA and the losses I got, it was already on my ignore list.
ADA is actually a good coin, they also increased very well in the previous bullrun season. If you got a lose in ADA, you probably have something wrong with your investment strategy. Have you evaluate your investment strategy?
