My desperation after becoming plus one here to own my bitcoin has grew in a week. The first journey was to look for the best wallet to use and Electrum becomes my choice. The account has been opened and I wait impatiently for my salary to enter this week to buy the first set and keep it.
On the second thought, I checked the chart of bitcoin to know if it's safe to buy immediately. My trading experience is weak but not so bad that I can't read the chart. The chart shows bitcoin is still going down, that made me rush to tradingview advice to be sure. The monthly advice shows that I should wait.
The reading of Neutral has more vote of 10 than the Sell that has 6 and Buy that has 8.
I will let this be my guide, will wait till the Buy has the highest vote. Money investment need to be carefully planned. This is just my plan, you can advice or give it kudos.

Why wait? Better purchase price? I understand your desire to maximize your profitability, but I think that these attempts to wait for the best entry point are a waste of time.
Just do it and don't worry. That's how I would say. This is not a call to action and you must make the decision yourself.
Some people can wait a very long time for bitcoin's fall even further. They wait and wait, but time goes by and they never buy. They live with some kind of naive hope that one day they will definitely buy as soon as btc becomes cheaper. Bitcoin drops in price, but they still don't buy and find new excuses for themselves. Don't be like that.
You are absolutely right that money investments should be taken seriously. But in the case of bitcoin, the rule works (so far it has worked) that whenever you buy, sooner or later it will pay off (it only depends on the waiting time). So, don't get carried away with a long wait to start.
