Don't believe it when someone says that your life will change through their advise and then all of the sudden will suggest you to buy a specific investment or crypto that they want you to buy or, they'll give you a link that they want you to visit and check the platform.
When it comes to money matters, you shouldn't trust any stranger. Sorry for those victims that don't even know the forum where it is the best place to ask first related to crypto investments.
if someone told you to buy the specific currency.. you should learn about that currency. just get to know to facts and figures.
ALWAY DYOR .. than just see the market cap.. and then buy it.. i think just ignoring someone's advice is not a good idea.
You can determine if that guy has a good intention by knowing the crypto that he has suggested. If that's a coin that's not really known and you're not familiar with it, it's up to you if you'll spend time researching about it but it's better not to waste your time from doing so.
It might don't look as a good idea for you but if you're just listening to a stranger that shills an altcoin that you're not familiar with and you found out that it's not worth it then you've just wasted your time.
