I am starting to invest in those lesser-known cryptos, the altcoins. If I'm playing with $2,000 that could vanish, how many different altcoins can I buy to get 5X of my money or lose it all?

Can you explain the USPTO patent application process and how much time it will take to approve the patent?

My friend and I want to start a business together, so what's the procedure to be followed for registration to start a business together? One more question: Is a partnership agreement paper really necessary?
