sometimes i read comments that i can't even understand where you even got the idea of saying those things!
What I observe is the price of these coins, how fast dash and ethereum growing
so are you trying to say that since the price of these coins rise fast that makes them good. that logic is broken my friend.
and besides if you take a quick look at the history of these coins and other 1000 coins like them you can see the same patterns repeat over and over again.
while we know bitcoin stuck somewhere and can't move any further
again, you are expecting an ever-rising-market and let me break your illusion and tell you that this kind of market doesn't exist anywhere in the world.
price goes up with more adoption and when it is fast there is a correction. and in small bitcoin market there are manipulations that causes a bigger correction.
since the problem still unsolved.
what problem?
the only problems that bitcoin has are FUD, weak hands, and spam attack which can not go on forever and the only result of it is a little bit higher fees.
the rest of the things you "hear" are bullshit and political to take the power and none of them will ever happen.
Another thing I notice : ethereum has been around for years and proven as good coin, it is reliable coin which offers good idea of course.
you are using words without meaning

how is Ethereum reliable?
it is centralized
and it has bugs and exploitable features.
you said good ideas. ok, which one of them you are even aware of? which one of them have you even used?
i have lots of good ideas too, but unless they become reality and put to use, they remain just that, "ideas".
Dash coin still unclear for me due to so many people said it is a scam project, but the price seems pretty high right now, so tempting.
price being high, in other words going high so fast is not tempting it is a big ass warning. a warning to stay away because there is a bubble forming. and it doesn't matter what market it is. Dash, ETH, BTC, Gold, Silver,...
fast rise means you lost your chances to get in, now stay alert because a dump is coming when bubble bursts. of course you can always still get in but the risks are much higher and you will most probably lose lots of money.
You are a wise men, and you really know bitcoin, yes, for now there is only FUD around him, with people like Roger Ver attacking the network because he is failing with ethereum. As someone said in the forum (i suppose it is iamnotback) dash's scheme is like steem's scheme, even if the price is going up right now, it means that an equal or superior dump is comming, slow but steady price rising means the coin is stable and adopted, which means that it is time to get in.
Do not forget that coins like Dash, ETH, are easy to manipulate, even bitcoin's price be faked, pick an exchange, any one with low volume and dump it here, you will cause the price calculators to show fake values, thus people who invested in bitcoin will sell, and it will create a mini dump.
As i always said, price isn't a reference at all for a coin, price is just what people agrees to pay to get the coin, nothing more, nothing less.
