Hey I'm looking to buying Bitcoin in amount of $5-10 M .
Seller must pass Satoshi text. If you got any advice or leads, it'll be appreciated.
Did you even know how much you are mentioning? $5–10 million is a significant amount of money. I can even say that is too much to invest, even though they said people should invest the amount they can afford to lose. I don't think you can afford to lose this money honestly, and again, this shows that you don't know much about bitcoin investment, and I don't think you have up to this amount. However, instead of coming here and saying you want to use this huge amount of money to invest in bitcoin, you should go to any exchange of your choice, like Binance, and buy your bitcoin there. You don't have to come here again and say you want to invest.
Investing more than $5 million in altcoins is a very scary and very dangerous thing. Knowledge about Bitcoin is very important. All of us traders here, I'm sure, already know what percentage of profits we have earned from when Bitcoin was launched until now. This is what makes many smart traders prefer Bitcoin to invest with the amount of money you mentioned above.
