Of course you can trade without experience and knowledge. It's simply either BUY or SELL. But if you want to achieve consistency profit in trading, that will take many years of experience and knowledge. Furthermore, it depends what sort of strategy you want to use to approach the market.
If you prefer more aggressive style of trading, then go for technical analysis and look for speculative or naked trading (Most newbie starts from here).
If you prefer more conservative style of trading and risk diversification, then go for hedging strategy which needs more math approach. You have to familiarize yourself with Delta, Gamma, Volatility etc., how to manage your daily position and profit mainly derive from market volatility.
Before I can trade without realizing my profit if I will still hold unto that money, many of my coins before are now on the moon if only I learn how to trade and I study first the market before , it is really hard to learn different things in trading because we can be wrong sometimes and experience losses but still this will account and considered as experience so let us study the market now because this is the right time for it.
It depends. I believe all people same as you including myself. I know the existence of Bitcoin since 2013 when that time we only mine with Asic USB miner. I bought 2 and started to mine but gave up because at that time, those new machine keep coming and anything you bought will depreciate very fast before you hit BE. I put almost USD 5k to buy about 48 pieces instead of mining at the price of around USD 110-120. I sold everything at USD 980. I am already a millionaire if I just leave it. Nobody can predict future. All I can say is trading is not as simple as BUY or SELL, both have different definition between TRADING and INVESTING. You need a lot of skill in trading, you just need positive outlook if investing.
