I invested a lot in Bitgesell (BGL) recently for the following resons:
- young, growing community project (official thread: https://bitcointalk.org/index.php?topic=5238559.0)
- influenced by the ideas of Silveio Gesell's idea of "Freigeld"
- deflationary (90% of transaction fees will get burned and as a Bitcoin fork there will never be more than the 21.000.000 coins available)
- still very cheap (around $0.02 per Bitgesell)
- Code is widely based on bitcoin code, so it is stable and reliable.

If you ever wanted to be a Bitcoin whale: forget it, its to late for BTC with almost $40.000 per coin but with something around $0.02 per Bitgesell you can easily be a whale in that nice coin. and who knows, maybe some day it will be the next x1000 coin. :-)

P.S.: Of course the coin is mineable and if you run a node, you take place in a weekly node contest and can win hundereds of BGL (https://bglcontest.bitaps.com/nodes)

Things they have to work on:
- List BGL on larger coin exchanges with more volume
- Promote it, so the currency can rise in the future
