Lastly, we look at Brett, a blatant Pepe rip-off, which did reasonably well for a while and fell from grace. Like the above, Brett is now at less than half the ATH it achieved in December. The jury is in: Brett and its fellow meme coins are fun, irreverent and culturally relevant. But they make for really lousy investments. Memes are great fun when the going is good, but in a downturn market, you want function.
