I think you are a bit confused about how finance works,
interest in dollars has absolutly no bearing on interest in euros that only becomes pertinent when exchanging one currency for another
and no one invests money that way.
My point exactly! So why do you use banking interest rates as an argument for how much cryptocoin interest one should have? Who's confused here?

Please don't accuse me for not knowing finance. I've worked as a programmer in this business since 1998. I think you just mixed up what I was saying ( /trying to say in a language that's not my native)

As for bag holders you're only a bag holder untill your price is met and i can absolutley guarentee that if somw millionare comes along
and offers 20 btc to 1 syn you will sell and they will take a stake in sync, so bag holding is areal moot point
Correct. But you will be more easy on the trigger if your Sync is in Bittrex already, and millionaires very seldom comes along and offer you anything at all unless they know what you have. E.g. at the market.
