Working on demo accounts or having paperwork has its own worth but practical trading always makes things perfect because with this any trader can gain experience which helps to increase skills in trading by controlling emotions and staying within strategy is a good thing as people often lose their patience which hurts them and increases losses.
Keeping an eye on the latest updates and having good interaction with current affairs is also an important part of trading because these things also have a good impact on trading usually people start panic selling due to rumors which are pretty dumb ideas especially for newbies.
Before entering into crypto trading having a good understanding of risk management also helps because Bitcoin and cryptocurrencies are highly volatile assets that can make you do the wrong thing.
It's a good thing to learn trading first through tools like paper trading simulator or through demo account but you will understand nitty gritty of trading only once you start trading with real money. It's like no matter how much you read about swimming, you can't swim unless you jump into real water. If you are new to trading then don't make mistake of jumping with large capital rather invest small amount first. It's because in start we all make mistakes and smaller is your capital, smaller is your loss.
