If i recall it was tokenads, betanclick casino online. You register, pay a minimum of 10 euros with your CC and place a bet. You must place the first bet for the tokens to be credited.
If it was easy, it'd be a boring game. It's already enough easy now and for this season i spent like 150 tokens.
That's what i made for this season. I bought 2 scouts (GK-AMC) then reinforced with 29,9 4* or 30 5* players (18-19-20 yo) from the very first market started after maintainance. spent maybe 20 total tokens for 4-5 players.
ever
For scouts, go to your transfers page, then click top right "scout" section, or "observer" or whatever your language says :P
To "token up" a player, click on him from squad, middle bottom you'll see the icon of the skill point, click on it. It'll open a screen where you can power level your player for X amount of tokens. but it's way expensive to do so.
