Big companies are investing in bitcoin in a clear way and they have a good long term plan. Regardless of the amount collected but remember bitcoin has never made any company lose if invested in the long term. So I don't need to explain the benefits.
Now if there are some rejections made by tech giants against Bitcoin that makes us less convinced? That's bullshit! No matter how they reject it because we have seen this throughout the adoption of bitcoin. Their rejection in the past has led to a stream of companies regretting it. Accepting or not a tech giant company does not make bitcoin weak.
I believe a lot of these tech companies are somehow already investing in crypto but in discreet way. Most won't disclose to the public that they are already into the market. Though some are open that they are into btc, however, I think most are still doing their business in closed doors.
