Big firms and companies investing in Bitcoin. Tesla, Micro Strategy and Twitter are just to name a few, pushing for global adoption.
Is this a sign for a long term investment or just pump and dump for them?
It is difficult to consider the influx of companies to btc as a "pump and dump scheme". Every visionary knows that the world is constantly evolving and changing, and since the start of the digital world (internet) that sooner or later, a new digital currency was bound to surface.
The btc train is a moving train, and most companies and individuals with enough resources are looking to join in and catch the gains, before the price value becomes stable. So i will say to the best of my understanding that to them, "Btc is considered a long term investment".
