I've held MARA for quite a while now and it has been one of the best performers in my portfolio. For me it was to be able to buy into the Bitcoin speculation without having to directly buy Bitcoin. Whenever BTC went up, Mara behaved like an leveraged stock and would rise more significantly. When BTC went down, Mara of course would follow.
It will be interesting to see how the market digests news of the new Crypto ETFs being approved into the mainstream by the SEC today.
Might be one to watch.
