Why it seems to be that this thread is all about hating and disliking bitcoin? you contradicted yourself when you said that bitcoin is overpriced and it's not yet expensive.
Bitcoin could be overpriced and could reach a very unreasonable price within this year and securing alternative coins would be ideal for all. BUT it seems like not all alternative coins are on trend and follows bitcoin some are have lost in time and noticeably not profitable at all, And this is why we should watch all the incoming alternative coins in the market as bitcoin is not yet that expensive.
And with those projects that you had mentioned, just like them I'm not also aware of their existence. I might take the risk of having bitcoin rather than going with a random project that's still on that phase of testing and still waiting to be listed.
