I got this too @Lightning so I'm now wondering if it might be worth transfering the €50k that I have in Trade Republic to take advantage of the higher rates? At the moment I have €50k in Trade Republic and €20k with Advanzia.
Right now the difference (3.75% versus 3.97%) is not huge but with ECB rates expected to decline, it might be worth moving money before the 30 August deadline to ensure you lock the rate until 31 December.
