2. I take the example of privacy coins like (XRP)
XRP (Ripple) is not a privacy coin buddy, maybe you referring to XMR (Monero).
I think he really meant to say XRP. That coin is centralized and not really private. Another tip is don't listen to the hype and shillers that will tell you a coin that you are not very familiar and tells you that it has the future.
Those kind of suggestions should be avoided if you don't want to lose your money. I've seen that before and never listened to them so I hope that others will do the same.
Yupss is right, like what you have explained and it is important for someone to always research before making a decision whether it is trading or investing in coins. Don't rely on random suggestions or what is said by cryptos experts, I only use it as reference material and nothing more.
Those "experts" that normally give tips aren't shouldn't be taken quickly. You have to analyze it and see if that really works on your side. Otherwise, be curious about everything they say in a way that you will not believe quickly.
A lot of gullible people about investments were victimized by those kind of people and they lost money so quick. Because after buying and making a small pump, they were not able to get out of it.
