I'll say this, when I actually used bitcoin I was never happy about the slow times to transfer coins. The constant fees being charged to covert to other coins. I won't talk about the money I lost at mt. gox but luckily I made money with NXT coin to make up for that loss.
I felt like I was constantly paying fees to exchange sites.
I didn't like the how bloated bitcoin has become, especially when I had to download the blockchain that was very large and growing rapidly.
I didn't like having any money sitting on the exchanges. I didn't trust the safety of my wallets with all the malware out there today.
None of these fears I have with holding stock and USD cash. Easily exchangeable to any other currency in the world with no fees.
I just don't see bitcoin taking off. It had its popularity with china, which I never expected china to allow it to flourish like it had.
Anyone trying to invest in bitcoin now are really taking a huge risk. If you want to speculate with digital currency then buy into another coin.
