You don't need to big degree or much education before you can invest in bitcoin, bitcoin is open for all to invest in. Since you said people living in the city, it means that they should be able to be somehow civilized to a certain level that it will be easy for the to know how to use andriod phone or a computer, meaning such people can invest in bitcoin. A lot of high level degree people have condemned bitcoin because they feel that they know it all and believe that it is impossible for bitcoin to survive, ignoring the opporturnity bitcoin is giving to them due to pride and ignorant.
To invest in bitcoin only needs the basic knowledge of bitcoin which you can be taught how to buy bitcoin can also be learnt. I believe anyone that can have a bank account and do his bank transactions himself either by going to the bank or via mobile transfer already have the knowledge to be able to buy bitcoin and hodli.
Normally one may choose to trade with his Bitcoin either he gain or lose is still his loss , Because one thing one need to know is that any amount of bitcoin you waste due to you trying to make short-term profits , may worth more in the Future. Like back then when bitcoin price was around $100 , alot of folks may have wasted their Bitcoin for meaning less things or loss it, without ever imagine seeing bitcoin at such price range it is now . Back then 0.5 Bitcoin would be $50, but now 0.5 would be In the price range of $30k now . You can see the massive difference so is better to accumulate and hodl , than to waste resources on trading your Bitcoin, especially when you don't have the knowledge on how to navigate trading , holding instead is keeping it safe .
