Definitely monero is secure, private, untraceable, and fungible as you said but as you said its blockchain has reached almost 40-50GiB in size and the size will grow as the transactions increases. So, I have some questions. 1. Will this not make its network slow? 2. Can this be mined by a CPU? Please clarify.
If the blockchain gets so large that only one or two nodes exist than yes. However, I find this very unlikely to happen since hard drive compacity gets cheaper with each passing year.
Yes and is much more effective than mining with a CPU on Bitcoin. It won't make you rich but you can at least still get rewards with pool mining. It is better to GPU mine though.
Thank a lot! You removed my doubts.
