Great post and welcome to steemit glad to see more people getting into the crypto world .So it can be hard to understand the technical concepts of bitcoin but not to worry because people on steemit are here to help you.As for investing in btc i would say is not the best time since prices are really high but even considering that in the long run it will increase simply because the market cap of all crypto's is just 500 billion which is essentially very little.But if you are just getting started with investing maybe dip your toes with some other cryptos and check out how it works never invest more than 5 % of your net worth because that's more than enough .Lastly know that the end goal is to make the world a better place and make some money for yourself along the way .Hope you like steemit.
