When will LN be 100% adopted, and will it be adopted before BCH overtakes market? or ALTS for that matter?
If you're asking if it will be adopted before BCH overtakes the market, the answer is YES. The LN had successfully tested and its now being adopted, on the other hand, BCH will never overtake BTC in the market even in the future.
LN is not even working yet! ..and its not being adopted by anyone... have you read the link above about btc going missing on LN mainnet?
