I've been wondering that myself. The highs and lows over the recent period have been quite scary, and I'm not even invested yet! However, I believe that the value of the good cryptocurrencies will rise over the long term, and therefore I'm going to stick to the principle of dollar-cost averaging and hope for the best!
Gold certainly has a more established and stable value than any cryptocurrency, so you might have the right idea there.
Which ones do you hold? Do you buy through Kraken.com?
I hold Bitcoin, ethereum, ethereum classic and litecoin myself.
Still waiting to get verified with Kraken! The FAQs state that the waiting time for verification is 2-4 weeks due to a recent surge in applications. It's approaching the fourth week now so hopefully I'll be able to start trading soon. I'm verified with a smaller, U.K based exchange called Cryptomate. However, their individual coin mark up is huge so I think I'll just hold out for Kraken
Good selection of coins. Are you tempted at all by the multitude of other Alt-coins? I will be looking to invest in Bitcoin, Ethereum, Dash, and Ripple.
If you could impart any other advice, it'd be greatly appreciated! I'm just trying to learn as much as possible at the moment.
