Lack of education, technical knowledge, and awareness has been the major challenge for Bitcoin enthusiasts
I don't need to understand technical things of Bitcoin, its open source code to use it. If you want to use it, it's simple than you think. If you want to use it more effectively, learn a little bit. If you want to engage in development, learn to code with deep technical knowledge. Different Bitcoin enthusiasts, different needs and different approaches.
We still need to understand the basic procedure of Bitcoin. Because without knowing the basic technical aspect of Bitcoin, we will be worrying for nothing. Like when your transfer is delayed, you might be worrying to death especially when you send a huge amount of BTC if you don't know about the transaction fee charges and the CPNP and RBF that will enable us to hasten the confirmation of our transaction if we accidentally send the transaction with minimal fee.
We know that money plays a major role in Bitcoin investment and adoption, over the time many people have complained that money has deprived them of the opportunity to partake in Bitcoin, after getting the knowledge of how the currency works, please my advice to every Bitcoin enthusiast is that no knowledge is a waste, you may not have the money to invest today, but learning about this technology is the first stage you have to cross in other to get the main thing.
You can learn with Bitcoin Testnet, use Bitcoin Testnet if you want to understand it, practice with its testnet blockchain before use it on the main chain.
This is a great advice which many of us forgotten. Most of us does not bother to use the Bitcoin testnet and immediately jump to the main net and do transactions.
You don't need to have money, it is not a mandatory requirement. If you have knowledge and skills, you can work to get bitcoin. You don't even have to spend money to buy it. Using money to buy bitcoin is only one of many options. Besides using your knowledge, skills about Bitcoin to work and get it, you can get it if you have a small business, a grocery and accept Bitcoin from your customers.
Money is the mandatory requirement if a person wanted to invest in Bitcoin. Even if he wanted to invest in knowledge, a person needs to buy the necessary devices to learn and process Bitcoin.
