Having a permanent job is better than investing your time in cryptocurrency because your income is secured and continous. Earnings in cryptocurrencies varies and it always contains risks because of volatility and price cycle. Presently, the cryptocurrency market is experiencing a bull rally because of bitcoin and many altcoins had continuing price uptrend but I still prefer to have a secure employment and trade only when there is enough time.
The best thing is to have a permanent job, but that one that leaves you the time to invest in cryptocurrencies and get an additional source of an income. By the way, the most successful traders work also (I do not mean in crypto).
I heard a lot of crypto traders get successful in here, and to think that are spending a lot of time in trading rather be in any social life.
If I have enough money to start in trading, I will definitely in fulltime trading but I don't have. It is on high advantage if we start in huge amount cause the possible we got will be also that big amount.
