Hello, I follow your videos on youtube.

If you are doing a video on strong alt coins for long term investing you cannot avoid those 3 picks:

Monero: Obviously the best privacy coin out there.

Bitshares: they provide a fast blockchain and a mechanism to create bit assets that track real life assets like bitUSD. The potential to replace tether makes Bitshares stand out.

Pascal coin: Wild pick. Pascal is using a different code base altogether written in Pascal. They designed the coin with a safebox which contains all the account and balance information. This makes pascal very fast 100 tx/sec and very scalable. You only need the safebox. You can see the safebox as a pruned blockchain. This is done by design.
Cons of pascal: mining is centralized and you need to get a pascal account to start transacting. Accounts are created alongside coins in mined blocks. The pascal accounts are already baked in the consensus. You need to buy an account from a miner. The pros is that the pascal blockchain is bounded by design and thus scalability and speed is achieved.
