Apart from the fact that these apps usually have to be downloaded from unknown sources, which is always a possibility of a malicious app, and anyone who has more such apps on their phone will receive a lot of SMS, which can be very irritating. As for payouts, I don't think it pays too much to withdraw $2 in BTC, these are actually dust transactions that will be a problem for the user when he tries to spend them.
I would advise an extra phone for all those who download suspicious apps, especially if they have a crypto wallet on their phone.
You have a point, but I've been paid multiple times by the apps and I can attest to that. One of them (MSMS) paid me
over 30 Euros in less than 2 years. And all I did was nothing.I'm also pretty wary when it comes to apps that sound too good to be true, but some of them have companies established and I'll always verify the payouts myself before recommending them to others.
SMS annoyance, yeah but after a while, you'd get used to it. After all, free pocket money. You never try, you never know
All these passive income apps are not worth it as you see @OP wants to earn 3-4 eth and with these apps he is not going to earn over them hundred of years also as they pay relatively very less as in your case also like you have earned 30 Euros or say only $35 in period of 2 years which is not less man and you get annoyed by all those messages all day.
As a newcomer if you don't have anything to do you can try them but speaking from my personal experience they are just waste of time nothing else and you get paid very less even lower to some faucets also.Speaking of MSMS they are also the same like the telecom companies have to test their services globally which they use your mobile numbers to send messages and pay you for the same but there are certain implications to that like
1) You may get wrong app from the playstore as it is available on Android devices only not for IOS devices or malicious APK files from the internet which could damage your device with virus
2) These services are not available globally in my opinion like some Asian countries, Canada,US and some other places are included.
3) If your country already have more registered users you cannot get yourself enrolled on the app to pay.

MSMS reviewSo @OP if you are interested in earning ETH then finds some other way like you said you are designer then what best you can do is to make any artwork and categorised them under NFT on the ETH blockchain as many projects are being launched and can easily gain momentum and there could be rush to purchase that NFT of your's and any other services offered by you to get paid in the same currency you wish to do so.
