The best crypto portfolio is not the one holding the most coins. It is the one built around where the money is actually going, and this week the money went into ETFs: spot Bitcoin ETFs pulled in $999 million on September 21, their largest day in 11 months, then $714.7 million on September 22, per The Block, a four day run above $2.31 billion.Portfolio building in a week like this starts with the blue chips and ends with one early stage pick.
