Those who wait for a specific price to invest are definitely making a big mistake because Bitcoin's movement or its fluctuations can never be predicted, but if you wait to invest, you may panic later due to Bitcoin's volatility, so you may eventually give up.
So consistency is the best investment decision here, invest as much as you can afford to lose, and no matter how small the amount, the goal here should be long-term, and the investment method should be to deposit Bitcoin through DCA consistently, but it will definitely bring positive results.
You can’t wait for a specific price before you invest in Bitcoin, Bitcoin can not be predicted and with the way Bitcoin is going you can’t wait for a perfect time to invest because it may lead to regret at the end, you can invest in Bitcoin in different ways and you can meet up with your demand or the amount of Bitcoins you want to buy, using a DCA method is the best way to buy when you want to meet up with the quantity of Bitcoin you want to buy, one thing i observe with some newbies when they heard invest as much as you can lose is that some think they can buy Bitcoin with any amount and be expecting big profits, the more you invest the more you earn profits that’s how Bitcoin works.
What of in rough times, I had a family friend who battled illness I had to be there for her and I used my little Bitcoin saved. I am not crying over it because I can still continue to save more the little way I do. I don't think about big profit now but continuity.
It's good that you saved your friend's life. Currently, you are a no coiner from the way that you sound and I would advise you to start your bitcoin investment immediately and don't delay because if you keep on delaying, you might regret about those bitcoin that you sold. If you have a discretionary income, share it into two parts, use on part to DCA weekly and use the other part to set up your emergency funds of at least three months of your monthly income.
You can be building your emergency funds and investing in bitcoin at the same time. Emergency funds is very important because it saves you from selling our bitcoin investment prematurely. If a real life emergency hits you during your accumulation stage, you use your emergency funds. You should also set up a reserve funds after setting up your emergency funds, you can channel that money into setting up your reserve funds.
If your discretionary income is not steady, there is no problem about that, only buy whenever it's available and plan to holdi for long term while you look for a mean to improve your income to make it stable that you can be consistent with your DCA and build your bitcoin investment for 4-10 years and above.
Don't say the action so in essence perform it. There are so many persons who just use their thoughts to invest and not their actual money and that's why it's important to buy and start up your investment immediately as possible, just as ruttoshi has cleared the basics, I think it's will a lot easier and better following the guidelines especially in the aspect of splitting your discretionary income into investment funds and emergency funds because emergency is something we dont hope but it's a constant in life and the best we can do is to get ready for it so it's won't set us on a different course in the line of our investment.
