The 𝐵⁡(𝐸⁢2;0+→2+) value in  
68
 Ni 
  has been measured using Coulomb excitation at safe energies. The  
68
 Ni 
  radioactive beam was postaccelerated at the CERN on-line isotope mass separator (ISOLDE) facility to 2.9 MeV/u and directed to a  
108
 Pd 
  target. The emitted 𝛾 rays were detected by the MINIBALL detector array. Not only directly registered but also indirectly deduced information on the nucleus emitting the 𝛾 ray was used to perform the Doppler correction, leading to a larger center-of-mass angular range to infer the excitation cross section. The obtained value of 2.8+1.2
−1.0×102⁢𝑒2 fm4 is in good agreement with the value measured at intermediate energy Coulomb excitation, confirming the low 0+→2+ transition probability.
