I found this explanation about why my rise coins number keep going down:
"Yes, it is normal. This is one of our biggest questions we get asked. We have a fixed amount of RISE (88 million) that we are distributing proportionately to all of our investors. Each time a new investor participates in the ICO, the amount of RISE distributed among everyone is recalculated and then redistributed. Each investor will see the amount of RISE decrease up until the last day of the ICO.
But... have no fear. Even though your RISE count is going down, the value of them is going up."
In this case, from what i understand, even if the number of coins are going down, i should still have the same value of coins in BTC/USD, But as you can see in this picture https://i.gyazo.com/add45cd8d42f60a0f828cf50bf160e80.png , when i multiply 30700*0.00000620 = 0.19034 BTC (so less than my balance of 0.19482355). so technically, im loosing money every day for now ...
Can someone help me understand ? is this how ICOs goes ?
You should stay away from investing and trading.
