Did you have a problem with it? Is it a scam?

I think blockchain is something we'll use everywhere in the future.

Even if lately there is lot of uncertainty around crypto (china, ICO, etc..), there is no doubt about the fact that every company in the world start to be interested by the blockchain.
And crypto will still know a lot of up and down but in long term, it will be bullish for sure.

So my advice, yes it's still the right time to get back on the crypto train
