asking for dropshipping marketing help

hello, i'm planing on setup a wordpress with woocommerce plugin to start a dropshipping store selling erotic toys, lingerie and sexual care.

i have a few questions, before i go into this kind of business:

a) this niche is still profitable?
b) is there a way to pay on aliexpress with paypal ? if not, is there a workaround ?
c) if i accept bitcoins as payment can i use them to pay in aliexpress ?
d) what will be the best way to promote the store (in very limited on my budget)

sorry if these questions are kind of newbe, but in fact i'm a newbe in internet business and marketing.

thanks in advance for all the help and information.

a) yes niche is profitable
b) some suppliers take paypal, most do not, you have to use a debit card
c)dont think so, but dont take my word on that
d)since your budget is limited, I would use massplanner and get traffic from social media

thank you for your help @QueenAshly
