To answer your question I can safely say I am no expert on Shariah either but have learned enough to prove the Adab Exchange are scammers.
"Profiteering" itself falls under the ruling of business which is to buy/sell tangible items and products to make profit so it is definitely permissible, however charging your customers any form of interest or usury is completely and strictly forbidden. The idea of long or short term trading (buying/selling) on stocks is not universally accepted as permissible. Some scholars have said it is allowed and some have said it is forbidden.
When it comes to declaring something such as this Adab Exchange as being Halal or Shariah compliant when it cannot be is just not on.
The funds to sell ICO tokens might be or could be coming from illegal and immoral earnings such as
pimps
prostitutes
porn actors
those currently behind bars in prison serving prison sentences
those that sell drugs/narcotics
those that manufacture, test and sell weapons
those that own publications online/print media cursing Muslims and those that have anti-Muslim agenda
those that own, transport or sells alcohol
If the Adab exchange scammers are willing to accept investment from pimps, prostitutes, porn actors, those currently behind bars in prison serving prison sentences, those that sell drugs/narcotics, those that manufacture, test and sell weapons, those that own publications online/print media cursing Muslims and those that have anti-Muslim agenda and those that own, transport or sells alcohol as well as those that promote, participate or propagate to suppress Muslims then the exchange cannot be called "Shariah" exchange.
Simple, this project is a scam.
i'm also not expert in sharia law, but:
- this is exchange project, they give you service, exchange site (marketplace) service. and they charging fee, not interest. fee is permissible
- short or long trading depends on exchange users, it's their responsibility to do halal/haram trading. this exchange just want to provide "sharia compliant" exchange
- ICO is one thing and exchange (its product) is another thing. and how u can judge ppl a thief, or "this money acquired in haram way" in this blockchain world? but even if we know "she is porn star", u still can accept her investment, although better to refrain.
