I’ve been buying stock (small amounts) of small charging networks because I’ve found they frequently get bought up by oil companies for far more than the stock is usually worth. Sometimes they’re used for green washing and sometimes they’re improved upon but at least I made a little money.
A network called “Volta” got bought by Shell which kinda sucks because they’re the most popular public L2 charger around here, so far nearly a year later they’re still in operation.
