Easy. Marinecoin.

Its way faster than bitcoin
It has support for AI and IoT, which is where things are headed
It is not too dependent on a core of dedicated miners or devs in order to work.  Most of the services currently provided by devs/miners to traditional coins will be provided by dedicated AI to the marinecoin network. This will have a significant downward impact on transaction costs and times
It's marketcap is below 1mUSD so it has a lot of room to grow
Best of all, it is currently free. There is an airdrop currently going on that will airdrop 90% of all available MTC to the first 20,000 people to apply and qualify. That comes up to 450,000 MTC free for each and everybody who wants it. Risk free.

Whats not to like about this?

How about a mega airdrop?

Go to marineco.in, follow the instructions, and you could qualify for 450k MTC free. That's 450,000 coins for free. If that is not mega, I don't know what is.

The question is, why should you waste your time on this?

First of all, its free, so you have nothing to lose
Secondly, this is not an everyday airdrop. This coin has been around for years. Its not everyday that a coin that has a history gets to be airdropped.
Thirdly, the coin has a low marketcap, so there is so much room growth
Fourthly, the devs are currently working hard on this coin, they've added AI support, IoT support, and so much more is coming online
Fifthly ... do I really need to give another reason?

Go to marineco.in for details on how you can qualify for this mega airdrop.
