Dont really know what to do

Hi everyone im a 19(M) from the netherlands which is looking to invest around 750 a month, now i could do this through the big banks like ABN AMBRO and do the NT world , Emerging and Small caps. Or i go to brokers like IKBR and De Giro, for ETFs like WEBN or VWCE. I really dont know what to choose at all FYI, this is longterm for like 20-30 years Thanks all for ur help submitted by /u/RestaurantAntique382 [link] [comments]
