I do not really understand what the intention was here but I think this is a great way to increase adoption. If one nation allows bitcoin or generally speaking crypto to exist in that nation with full support and spreads that same feeling towards other nations as well that is a great thing.
I think the intention is very simple, promote bitcoin in there country, imagine Obama gifted Trump crypto I'm sure it will send a strong signal to the whole world.
The first thing a president or anyone who is in the lawmaking process hears about crypto is a very important thing, if they hear about it like "hey there is this new thing called crypto and it is great because..." that would make them be more supportive unless given any other reason, however if they hear "there is this new thing called crypto and it is horrible because..." they would be against it until given a reason not to and that would take us longer time to make them accept it.
First, Estonia is very small compare to other EU nations and maybe that's one reason they started to welcome to attract investors. Second, it looks like very successful move at they have attracted a lot of startups with their progressive approach. However, they are amendments on their crypto regulations, it strict so I don't know if projects are going to move there or choose other crypto friendly nations. Specially with the money laundering scandal that rocks EU recently. But it still good that they remain very supported of bitcoin and blockchain technology.
