2) Review your portfolio every 60 days
It is easy to chart your progress and see which way your portfolio is moving. As traders follow their strategy, it is advisable to keep an eye on Bitcoin price and its market capitalization. As Bitcoins price increases, its market capitalization increases and this leads to a fall in altcoin prices. This means it's time to hold or exchange for Bitcoin.
I dont believe the 60 days tag, it might not necessarily be 60 days if the plan was to take profit. In the past 2 years it had not been easy with taking profit from bitcoin. The idea for bag-holders is just around 2x-3x of investment, this could be difficult to sell if higher because of the volume and exchange listed. It is always difficult to stay away from internet when the market is doing fine and most of your tokens are kept in wallets not exchanges.
