It's always sad to miss this type of threads here. There are market experts in the forum better than any other trader outside. Anyway, it's bad for IOTA to be passed by Cardano ADA project, but it's still alive. The future is bight in IOTA because IOT market is great.
If you have done your analyzation properly and you may be bought a lot of IOTA. Iota has used the same system like byteball. Both are using DAG system which uses the server to verify the transaction.
The byteball has the same method as what already done by iota. The blckchain less system can become alternative but the main thing about that pegged to the server. That makes the zero fees.
Have never looked deeply at byteball, but iota is feeless because every tx confirms two other tx--not sure what you mean by servers make it feeless. Also, I think they have different designs, based on discussions on BCT (chiefly between ComeFromBeyond and anonymint) there are different attack vectors between the two. Not every blockchain is built like Bitcoin, same applies to DAGs, so distinctions should be clear.
