There are many alt-coins that have the same blocksize limit issue as Bitcoin. If you are looking for a proof of work coin that does not have a fixed blocksize limit baked into the protocol then Monero https://getmonero.org/ is my choice. It uses adaptive blocksize limits that allows the maximum blocksize to scale as the coin grows over time. Now we are dealing with a coin that has less than 0.13% of Bitcoin's market capitalization so one could also add a non crypto component such as fiat current or precious metals also into the hedge. I found out about Monero last year because of the 1MB blocksize issue and have a position in Monero.

The key here is to do one's own research first before buying or selling.
