There are two different philosophies and methodologies followed in managing the portfolio of digital currencies.
Diversification of risk
Maximizing the number of Bitcoins
1- Diversification of risk:
People who advocate this method believe that you should not keep all your eggs in one basket. It means that you should not keep all your investment in a single currency that if its value drops you will not lose all your money. For this purpose, you are required to select 15 to 20 different potentially good currencies and invest in each currency 5% to 10%. If at any time your investment in a particular currency increases above 10% you should think of it to break it down within 10% limit. By following this methodology you will not lose all your money even if a particular currency drops to zero. It means you only lose a maximum of 10% of your portfolio if particular currency even drops to “0”.
Doug Polk is the follower of this methodology. Here is his youtube channel.
