Buy coins for $ 100 and a year later to sell them for $ 120, this is not a long-term trade.
It is necessary to invest millions, so that after a long time they will bring profit.
All the rest is nonsense.
And when you do not have money, but there are a couple of coins, you can just sit and pray that they will grow a thousand times.

What do you think about Blockshipping ICO?

The blockchain based GSCP platform is the world's first freight container registry and the first global platform allowing all players in the shipping industry to perform a wide range of transactions related to the handling of containers. The GSCP ICO opens in May.
I took them already for bounty campaign because I want to take as more as possible their tokens. Via bounty and token sale.

“The GSCP platform will enable a savings potential for the global container industry of at least USD 5.7bn per year.”
“The GSCP platform is expected to reduce the global CO2 emission by at least 4.6 million tons yearly.”

Seems like really cool project and they have quite good and experienced team.
Looks promising. But check it for yourself.

The ICO starts  14 May 2018 at 2 pm CET
