Market price in some cases are unpredictable because I have heard of some one buying a coin in a certain rate, but just for sometime it get reduce to a lower rate,so market price is unpredictable
That is the reason why you don't have to buy with a short term mindset ( trading) because the market is very volatile and so buying with the intention to sell very early when the price appreciate is a total waste of time and it is more like a deceit because the chance of it happening as predicted is not known or certain. So to avoid all these, it is advisable to invest in Bitcoin and hold it for a very long term at least 4-10 years and if been carried out properly, following all the procedure there is a possibility you will see something great because Bitcoin potential is always seen in long term of holding.
Well trading, investing and then holding for long term all are different things and I think one should have certain portfolio fix for each type of these strategies and plans.
I'm saying this because a trading especially the spot and the future trading one will get short-term profits and that will make him satisfied and happy and he will not touch his long-term portfolio. In this way he can enjoy both the perks of short-term and the long-term gains.
What you should understand about trading is that it's addictive and tends to mess with your emotions especially if you're losing which might prompt you to throw more funds into it in a bid to recover and who knows, the next available funds might be your Bitcoin portfolio and you mess things up for yourself.
To be on the safer side, it's important you don't mix trading with investing. I believe most guys would agree with me that it's more peaceful and relaxing when focusing on investing and increasing your aggressiveness when you've the means rather than sourcing for funds to put into trading separately. The focus is on getting more quantities of Bitcoin and on the long run, the profits from the compounding effect of Bitcoin price appreciation would even be far greater than the quick profits from trading, that's if at all you end up profitable and not messing things up totally for yourself.
