I buy and sell Ether everyday and make a profit of 50,- - 100,-

with that money i bought Iota last week and now i have 10k dollars and started with just 2k on 11th nov.
Altcoins are great
But most time i dont understand the pumps on bitfinex.
In what exchange do you buy it? Eth everyday wont go 430 ---> 480
Its hard to count your profit with only ETH, or you are magic, unbelievable luck
