Bitmain Antminer T15 or Bitmain Antminer S11

Hi guys !

I’m new to this crypto thing…i just joined the community from France.

Is it worth investing in a Bitmain Antminer T15 or Bitmain Antminer S11 knowing that I can get electricity for free or at 0.16 euros/kW in worst case scenario ?

Can we miner using cloud like Amazon AWS ?

What advice of hard would you give for somebody who is willing to start with 2500 euros.

Thanks,

Best regards,
