Well; not much has changed
1. Bitcoin remains the best and there are 0.1% bounty that pays in bitcoin
2. Altcoins emerged as a quick rich form of investment; there are several pump and dump tokens
3. Regarding merits, the forum placed a new rule, newbie now needs 1 merit to get to junior member so as to improve the quality of discussions on the forum and so far it has worked I believe
4. If you go through the thread, you will realize that there are several Blockchain platforms under etherum, stellar, Blockchains and a lot of scam tokens too
5: I can say airdrop programs are technically dead because they bring no reward whatsoever (rewards are in 0.1$ - 1$)
In a nutshell, be careful now; frauds are everywhere, remember the simple rules in keeping your private key to your self
I guess this sums up everything that has happens in a year and to add more there is new crowdfunding called Security Token Offering and people are checking if this is the one that's going to replace ICO because it's more regulated and guaranteed safety to investor's investment, we'll have to see that happen.
