is showing your interest and curiosity about Bitcoin. By the way, you are at the very right place to understand what bitcoin is because the Bitcointalk forum is that place where "Bitcoin Talks".
I have a very simple question on Bitcoin:
What are the principal technical skills a bitcoin lover needs to have if I want to buy a large amount of Bitcoin and hold it for long-term purposes?
My suggestion
Major focus on the security issue, but all it needs principle understandings, which gives more outcomes possibilities of breaching. The second thing to use bitcoins for increasing assets values by implementing in many platforms such as Defi, Yield farm, Liquidity pool, lending, borrowing, and trading etc.
Right now the second layer of blockchain for many other chains including cross-chain networks has created a tremendous wave in the market. So, understanding Bitcoin, Blockchain, and Cryptography in depth will definitely make you richer in the upcoming future for sure.
