Thanks for the helpful tips, all of which - not least the contests - I'll be following up on. If it really is a case of "how much you put in" that's great news. I was getting the feeling it might be "who you know" or "how much CASH you put in". A combination of all three, perhaps. I'd picked up on the crypto thing, though I'd assumed it was just the big hitters who were attracting the big bucks. Fortunately, unlikely candidate though I was, it's an area that's come to fascinate me strangely, so even though I'm no expert maybe after trying the commenting strategy for a week or two I'll start with a half-jokey 'My first three months of crypto', see if anyone's biting. Investigating the mysteries of Steem (same as Steem dollars?) and SP (which I know must be Steem Power) are my next job, however. I assume these are key to how those who make the really decent money do so. All good fun. Thanks again - really helpful to hear your thoughts - and good luck to your own eandeavours.
