I found Brokerstorms which is offering exchanges powered by Betfair with BTC deposits and withdrawals. Though not sure if they can be trusted. Are you familiar with Brokerstorm and their exchanges?
Yes, for most, if not all, of these WLE, you would have to go via an agent like Brokerstorm for example. This does not sound very attractive and is a hurdle not everyone is willing to jump. On top of that, you would also have to do KYC (with the agent). An agent sounds like a shady person sitting in a dark room under a lamp smoking a cigar
In reality these are more or less normal companies, who maybe operate in a bit of a grey-ish area. But a lot of gamblers, even without agent, operate in a grey-ish area themselves, so no reason to worry imo.
If you find a trusted agent, you can have accounts at bookmakers/exchanges, where you normally wouldn't be able to play. There is just a middle-man, who connects you to the bookmaker/exchange and all money transfers are done via him. Please note, that all agents have a minimum deposit, so this is not for punters that play with very small stakes. The minimum is 100,- Euro (or equivalent) for most of them. In Orbit Exchange you have a minimum stake of 7,- Euro then, which has to be considered as well (if you lay a 1.01 for 7,- Euro, you only have liability of 0.07 Euro though, so you can actually play with less than 7,- Euro too).
I don't know Brokerstorm tbh. I have my Orbit account via
Bet-Football, but they don't offer crypto payment. Another agent, which I have/had in my portfolio, is
BetInAsia, who offer Orbit accounts and BTC payments, so maybe you want to try them.
Pre-match trading is a good way to learn the game of trading, since everything is rather slow and you are not in danger of odds going against you fast. You can stake big-ish amounts, without being too worried. But otoh the markets don't yet have the volume, like they have inplay of course. It gets better nearer to kick-off though.
A very good pre-match trader is Caan Berry. Not sure, if you are interested in horse racing - I am not - but there is still something to be learnt from him:
[Screen Recording] SIMPLE Betfair Trade of £70 PROFIT - Caan BerryHorse racing is very good sport to trade pre-match, as are the the big football matches (look at correct score market) and probably cricket, but not sure, since I have no idea about cricket.
Which sport are you interested in and want to start learn to trade ?
