I recommend using the Crypto.com app’s recurring top-up feature. The “fees” are pretty low on most tokens since it’s using the spread from their exchange to buy. Once you have bought a token, lock it up in an “Earn” term to earn interest on it.
I locked up some CRO and am now earning 14% APR on USDC. Pretty happy about it.
Guessing it is between Crypto.com and Kraken then. Both look good but I will try and work out which I trust more as it seems I can get similar on both but obviously will research a bit more. Thanks for the advice!
There’s no harm in signing up for both tbh. Dig in
There is no desktop version for Crypto.com but from what I remember you get 30 days free fees plus a sign up bonus.
Coinbase has a desktop version and you get £7.50 free bitcoin. There is also several videos to watch which will give you free crypto.
(Note: coinbase has the best and simplest interface - just my opinion though).
Now your just making it harder 
I’m not bothered about desktop to be honest all I want is the cheapest, simplest way to deposit small amounts which I can leave and hopefully increase the value. I just can’t find a comparison for those metrics.
Pros and cons to both I’m afraid. You could go for both. I don’t like to have anymore than 5k invested in each crypto exchange thats why i have more than one.
I did have Binance as well but hated their interface.
As has been said, go for both. Best of both worlds.
Think I will go with both then 
On a similar subject I was talking to a friend about this subject and they said they were thinking about something similar to the link below but I thought a bit dodge. I remember someone around here suggesting a site that may be similar. Anyone know what I should tell my friend and if there is a better option.
Edit link helps
Not sure about this. Youll probably earn pennies and have a hefty electric bill
stuff like that is only profitable if you don’t pay electiricty imo.
or, if you could make an app, and get thousands of people to run it at their own electricity cost, then it would be very profitable
If you want to mine crypto try Pi or Bee on mobile. Their in beta and not live crypto at the moment.
(Disclaimer: I am not endorsing either of these tokens nor promoting them. Just another option for those who would like to mine).
That’s what I thought but was interested in opinions before I go and say it is all BS My theory is you spend more on power and machinery dying than what you can earn.
There is an active app/miner already in circulation… electroneum - https://electroneum.com/ I had it in very early stages not opened / downloaded the app again for quite some time. They had some contracts going with some virtual mobile operators to use ETN as payment for calls/texts/airtime in places like india, africa etc.
why do you prefer Kraken @Alex5 ?
For the staking options and easiness with staking/un-staking; I have Polkadot, Cardano, Ethereum and few Kava that are generating weekly staking reward.
On crypto. com I think you can only stake CRO, which it is their native currency and it is locked for months. While on kraken staking and un staking is almost instant.
Ultimately which exchange is better for you depends on what you want use it for. Crypto. com offers Visa card with cash back and more exotic coins that are not on kraken - like vechain, avalanche and phantom which I would like to buy.
100%
So the standard Kraken would be fine to do this and not the Pro option?
Yes, I think kraken pro has some additional feature for trading but not additional cost attached. You should be fine with the normal version.
For some reason I can buy/sell from the app on the phone, but in order to stake I need to use the web app.
You can stake CRO for the card or reduced trading fees. You can also stake a whole number of tokens, including stablecoins like Tether and TGBP, in addition to popular tokens like ETH and ADA, which earn between 2 - 14%, depending on the token, your card tier, and the lockup period (flexible, 1 month, or 3 months).
