Byteball has still good potential to grow, there were 2 DAG currencies that increased a lot - IOTA and RaiBlocks and Byteball is currebtly the most advanced DAG crypto with working wallet and ecosystem and I expect it would be between these 2 in terms of market cap - this means the price of Byteball would grow further. There is additional airdrop planned for Byteball holders (+0.1GBYTE for each 1GBYTE owned) as well airdrop if you have linked your BTC wallet. I would recommend to wait as the price will definitely go up.
