If the reviews are good then I think it's worth trying, also one has to be precautious cause it won't make sense to lose funds to a company while trying to recover lost funds through them. Anyways i took a little glance at the  site and saw that their services is not only concerning Bitcoin but other cryptos too and  I'm really impressed but my qestion is, if someone used an address from a watch only wallet to receive a token, can it be recovered by this company too?
