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?
If what you want to do is just holding, then there isn’t much that is required ,all you have to do is to know your way around the wallets and that does it. Unless you want to be able to predict the prices in future then you can study technical analysis and fundamental analysis. This could be useful if you would like to be able to know the right time to make your investment and went to sell. You just have to understand how the market really works that way you will know when there is greed or fear and went to take actions. Knowing technical analysis will also help you if you decide to go into day trading later on.
if i may add, buying large amount of bitcoin would need how secure is your wallet is. with this situation, don't store your
BTC in exchanges (not even in top exchanges), better store it in your own wallet, hardware wallet if possible. there are many tutorials already on how to do it. as the OP said, he had learned a lot from this forum already and adding more knowledge by roaming around here and checking in the beginners & others section would greatly help in his journey. also, as a beginner, better start understanding the market using bitcoin first. and then other alts can always follow. because things will get complicated once he explores his opportunities in those countless number of alts. so yeah, i can't say you need skills to hold btc for long-term, you just need to know how you can secure your coins and not to be scammed by substandard exchanges.
