anyone?

Hello all,
i'm new to Bitcointalk (my first post!), but not to bitcoin. was holding myself from entering since 2012/10$.... yea i know, whatever.

i actually opened an account here now since i see some projects getting momentum, that involve other technologies than blockchain, such as DAG and Hashgraph and are said to be superior.

i guess here would be more appropriate to discuss this, as Reddit is a bit too focused on market trends and price.

so what are the opinions for and against? i'm curious to hear the tech people's opinion.

thanks!
