Seriously, what did you expected with a coin named marijuanacoin, i am not the kind of guy who judges coins by their name, but here, it was smelling scam at 100 km around.
People should have more serious criterias regarding their investments, in this case, regulation would have been usefull, especially to retrieve people's money.
Not sure from your post if you're taking about marijuanacoin MAR or Marijuaneum XMJ which this thread is about. You use marijuanacoin MAR in your post.
Any coin can be a scam, but MAR actually looked good. Had a great wallet, website was nice and integrated with a web wallet, roadmap was do-able, custom block explorer, and he did the burn of the unsold coins.
IMO the coin was pretty good. I even overlooked that he left his first coin NUC.
Marijuaneum XMJ on the other hand, is a total scam.
MAR's dev fled with the ICO coins, read the other posts.
Besides of that, do you know who made the wallet ?
You should check this post, most of the wallets here have been made for scam projects :
https://bitcointalksearch.org/topic/winqt-best-design-wallet-check-my-service-1434314This guy is making most of the nice wallets you find in these ICO projects, does a nice wallet means the project is legit ? no, why ? i am an early miner of Ethereum, and when it started we had to download two files, Geth and Eth, Geth been the RPC client for mining, and Eth the wallet and syncing client.
Look at what it is today, but it means that a project with an ugly/basic wallet can be as legit as a long time established project's wallet.
Have you used the bitcoin core wallet ? it is a basic wallet display.
