Before you talk about capital then ultimately you have to look at yourself in this context your readiness whether you can or not to trade.
If indeed you can do it even for a smaller capital than that it will be very enough but if you only make instincts as a benchmark that bitcoin will go up or down not just 1 million even 10 million of your currency will not be enough for your trading.
Because what? Because you only make instincts or even look for them traders share signals without knowing what you are doing and just entrust yourself to others.
Maybe in this case there will be an excuse for the learning process, it may be good but in the end this can also be refuted because being in trading is not as easy as imagined considering it takes a long time to learn this and of course things like this are not worth it if it is just said to be just trial and error.
You know only trading will not solve it truly. In blockline life all coins are so much volatile, all you will find wash trading, regulatory changes even unexpected hacking shit. If you lazy to doing proper trading course and don't have any strong money management mentality something like risking 1/2% each trading, proper plan when to entry ot exit then it is sure you are gambling on your money. so it is not sustainable in any aspect. Man if you are serious then consider it as strategy, learn every rules properly and apply while trading, by which you could protect your funds,
You either develop a disciplined system, or you fail by relying on gut and hype.
I don't really care what the block line says or whatever it is in trading because the choice is only 2 for the OP if indeed he wants to make trading an option then he must realize that there will be a lot of things that must be prepared including mentality, learning and all forms of things from technical and fundamental that are all related to trading and of course this takes a long time but of course this is another form of risk that must be accepted because it is like a thing that must be done as a process to support the goals he wants to achieve in trading.
But if the OP is not able to do this then just relying on capital of any size according to him then all will be in vain. Because he does not want to learn trading and is only focused on profits and has the mindset that with big money he will get a big win too but in fact it is certainly not as easy as he thinks.
Maybe this can still be done for some people who have strong instincts but in the end things like this are just waiting for time because sooner or later it will run out soon.
