to be expert in the bitcoin world, not just to understand what bitcoin is, and just be a bounty hunter in this forum, but also have to do things like altcoin trading, mining, invest in ico project, things must be learned if you want to be an expert in bitcoin world
Yes, you also need to be aware of the alt coin and how they are doing. Just like how ethereum is posting a thread to the bitcoin as some say ethereum will overtake btc. The reason is that ethereum has smart contract etc. On the other hand, btc also have many problems it faces. The recent bitcoin cash fork can cause potential problems to bitcoin like how miners start to switch to bch and btc transaction got slowed down. On the other hand, btc also has high transaction fee, like 1 had to pay like $6 fee just for a $3 coffee. So btc are currently undergoing transformation and hopefully with segwit 2x and lightning network, btc transaction will be immediate and cheap. Also, privacy coins are getting more and more attention. Will it be a day where privacy will also be needed in btc?
