I was away from crypto for years and now I'm trying to get back into the game.  I was really STUNNED that there is no exchange, even after many years since bitcoin started, that we can just deposit USD and start exchanging altcoins.  I hope I'm wrong because this would be the single biggest hurdle for altcoins to be widely adopted by general public.  There are just too many hurdles to jump over just to START trading. 

Why does coins prices fluctuate so much and it is never been constant making predicting price much harder and much riskier and holding on to coins can be the best way right now.

why does it change prices constantly and never stagnant?

Hi guys, there are so many ICOs, such as those listed in https://www.coinschedule.com. It's pretty hard to review them one by one.

Which elements I need to consider, the team? the product? the promoting technology? or something else?

Thanks for any suggestions

Let be real. How many of you guys actually read the whitepaper? I read whitepaper sometimes, but reading multiple of them can be a burden and a headache. Do you guys got any tips on getting through whitepaper a little faster. It killing a lot of time. Thank.
