Permissible and impermissible items of trade

Selling agharbatti and muti products

Q:

1. Please advise if it's permissable for one to sell traditional muti products, such as tokoloshe salts, oils, soaps, etc, many of which has the following phrases on them (go away evil, money drawing, sangoma, luck , etc.)?

2. Is it permissible for one to sell agarbattis with the same phrases as above?

3. I work for a wholesaler that sells these products together with many other cosmetic products, part of my job is to purchase, sell, capture on the system and promote these products, is my earnings haraam?

Selling wigs

Q: Is it allowed to sell human hair as wigs as well as plastic hair as wigs which is sold in cosmetic shops. I understand that there is some fatwa regarding it but to my understanding the Hadith states that we cannot sell it or wear it. Please clarify the matter.

Selling branded items and trading in shares

Q:

1. Hermes is a fashion brand and its name was taken from a Greek figure. However, the bags do not have the Greek symbol for Hermes. Is it permissible to sell the bags anyway? What I mean with Greek figure is Greek 'god' (their words, not mine).

What about selling Louis Vuitton bags or Jordan Sneakers. Their name doesn't represent a 'god'. Just a person. 

2. My second question is about day trading. First of all, is day trading stocks (non-haram businesses) permissible. And what about day trading crypto. So, trading ARK for BTC. Both are cryptocurrencies. Is this trade a form of riba because it seems like it is a 'gold for gold' trade (both cryptocurrencies, but they have different values and meanings).

3. You said that investing in halal companies is permissible, however the interest that they are involved in is totally forbidden. But does that make my earnings forbidden (and does it come in the category of 'witnessing riba')?
