First of all you need to know the difference between trading and investment, investment is when you are accumulating Bitcoin and HODL for long while trading is buying now and see out in a short while so advising some one to go into full time trading in other to secure their future is wrong you will definitely put yourself into more pressure while trading because you will consistently be cheeking to know when there is dip or not in other to sell out.
Accumulating Bitcoin and HODL for long will give you mind rest rather than trading, traders actually make profit while trading But the risk involved is much compare to long time holders so it is better to accumulate Bitcoin and HODL for a longer time instead of fucking around trading bitcoin which is meant to be an investment.
Therefore, instead of wasting time by trading, we focus on investment.
You are very much correct here and I think that you are not the only one that thinks such way, trading is a complete waste of time energy mostly if you knows nothing about the craft, and why it is very dangerous is that you can lose all your hard earned money just in a twinkle of an eye, but with Bitcoin investment reverse is the case, you can make a fortune from it
if you can hold for a very long time, it doesn't matter if you are a newbie investors of not, once you have the basic knowledge on how to buy and what is required to hold effectively, like having a source of income and an emergency funds to sorts out any emergencies that may arise in the future, you are good to go, so it is very important that we focus more on Bitcoin investment than taking stupid risk trading our hard earned money.
