... I don't know much about Bitcoin so the person gave me the link to this website and suggest me to know about the various opinions of users on various topics. Since I see that Bitcoin is always discussed , I want your suggestions about my Bitcoin investment.
Should I invest money with the suggestion of that guy? He told me that if I invest I will get good profit. He said, he will open my bitcoin wallet and help to buy bitcoins. Should I invest in bitcoin?
As long as you can take a risk like how much are you willing to spend just to have a ride with this market investment, like your friend said you are willing to lose, if you think you just want to try and getting afraid with the 500$ you can take a 100$ or less its up to you so you can test it out if this market or crypto itself is suitable to you or not, time goes by you will learn a lot from your experience or even experience of other people here. Bitcoin is the most ideal for beginners and if you want to take another step altcoin is.

In this part I don't trust, don't let anyone have your wallet and manage your money, let yourself make decision,s not them and even your known person once they see a big amount of money anything can happen. Don't trust anyone in terms of having your wallet.
