Back into Cryptocurrencies
August 7, 2017
Recently, I got back into cryptocurrencies. I got interested in bitcoin around 2010/2011, did a bit of CPU mining on my laptop (never won a block) and got ₿0.05 bitcoins for free from the Bitcoin Faucet (now worth about ~$150). Bitcoin seemed a very enticing alternative, given I was living under capital controls in Iceland at the time. However, bitcoin back then was super niche and the utility had not yet materialised. With time, I lost my bitcoins and mostly forgot about them but stayed loosely up-to-date over the years. Until now.
This blog post was put together after a few exchanges on Twitter:
Getting Started
I recommend reading through the getting started guide on bitcoin.org. bitcoin.com also has some decent supporting material but it seems to be a business pushing its own agenda. Roughly speaking the process is as follows:
- Create a wallet,
- Sign up at an exchange,
- Send fiat money to the exchange,
- Buy cryptocurrencies on the exchange,
- Immediately send to your wallet.
Wallets are how you securely store cryptocurrencies. There are varying types of wallets that serve different purposes:
- Hot: Mobile phone wallets.
- Cold: Offline hardware such as Trezor or Ledger.
- Deep freeze: Private keys or wallet recovery codes (12-24 words) printed on paper.
Hot wallets are for your daily spending. Do not store more in them than you would carry around in cash. The wallets I would recommend the most are offline hardware wallets. Long term, the safest option in my opinion would be laminated paper (to avoid water damage) wallets stored in fireproof safes at a minimum of two locations. Another interesting deep-freeze option is engraved stainless steel.
Do:
- Use offline hardware wallets as soon as you can. It is the safest yet practical option out there.
- Write down the 12 or 24 word recovery phrase when creating a wallet. Do not skip this! It is a way to recover your funds if your phone/hardware gets destroyed, lost, or stolen. These words should be written down privately. Anyone with access to these words can use your money.
- Follow Andreas Antonopoulos on Twitter and especially YouTube. He is incredibly good at explaining bitcoin in simple terms.
- Be paranoid. You can probably not be paranoid enough.
Do not:
- Use a wallet on your personal computer. It is simply not secure enough.
- Keep fiat nor cryptocurrencies on exchanges. Exchanges get robbed and seized.
- Day trade cryptocurrencies unless you know what you are doing.
- Worry too much about when to buy. Just buy frequently over time and hold.
- Mine cryptocurrencies for profit unless you know what you are doing. Mostly profitable on special hardware in datacenters.
What I do
- Exchange: Kraken.
- Hot wallets: Jaxx & Copay.
- Cold wallet: Ledger Nano S.
I look at bitcoin as a long term (5-30 years) storage of value: digital gold. Transaction fees can range from €0.5 to €4, so the only thing I will do with bitcoins is to hold on to them, buy other cryptocurrencies and maybe take part in ICOs. I will look into other currencies for utility, like buying and trading things.
I do not hold any allegiance to any specific cryptocurrencies. My strategy so far is more or less to "buy into crypto". That means I split roughly on total market capitalisation of each coin:
- Bitcoin: 60%
- Ethereum: 20%
- Alt coins: 20% (litecoin, etc)
Personally I do keep a maximum of €200 on Kraken. I accept the risk of losing it but in return I have the option to buy more on short notice (when price drops). Furthermore, I never invest more into cryptocurrencies than I would be okay with loosing entirely. A hard earned lesson from the 2008 financial crash in Iceland.
