A very risky strategy.
You are using tokens that are valuable to bring in a free agent, so hoping that you are the only bidder otherwise you will lose the tokens in a biding war.
Hey mate
No, there is no risk at all if you 're experience with that.
I 'm playing like this for 6-7 seasons now. My tactic is to buy mostly young expensive fast trainers. They need a LOT of money. This season (12) I payed about 400M the first day, to buy 8 nordgens. I had to renew my team, I sold the older ones (23-24 y.o.) and bought the next gen.
I have Tokens but they aren't value for me. Most value have the reds & greens. I use T to buy free agents so can earn money for my nordgens. I avoid to get involve in bidding wars and always have an empty position in my team for free agents. Anyway, a team of 18-19 players is enough to have a complete team.
Being at lv12 now, I have no problem yet to sell my fa. So, when I buy a fa, I don't bother to train him or to qualify him for negotiation list, just sell him asap.
I just have to be careful when the things will change - when I 'll reach higher levels.
