Bitcoin HODLing for years can not be a lost affair.
If you know the recipe for how mostly are making profits through holding Bitcoin as you've said, then why not do what others are doing as well?
You're good to trade for profits whether it's on a daily basis or weekly basis but don't let yourself have any Bitcoin that's set for long-term holding. It is what it is but those that are dominating this market are the people who have experienced the toughest times of the market and learned how to be the most patient people in the hardest times.
If I were you, I will buy bitcoin at its current price, and if by July, the price become cheaper, I will buy more to bring my average buying price down, remember, this market can't be predicted accurately.
Yeah, if he's just here til' July then he should take advantage of the moment that he's seeing. Buy and decide to sell for that month if the market goes better.
In this market, it is all up to us how we will prepare for the future.
We may have seen some people holding for long-term because they have reasons.
You can read various insights from newcomers as well as long timers, but at the end of the day, it is your decision to make.
It is your own money, so you should decide on what to do and not follow other's suggestions.
But of course you can always gauge and asses the insights you can read over the net.
You are completely right bud, it is always our personal decisions to make at the end of the day, as we all already know that if one follow the advice he found on the Internet, and maybe things later didn't go as envisioned, there is no way such person would hold the one that gave the advice responsible, reasons being that..
1. You don't know each other, and neither have you ever meet, and chances of meeting is even slim..
2. You were not forced, you read, and on your own decided to do as advised.
So basically, it's up to OP to decide what's best for him, is his money, is his financial life and it is his sole responsibility to plan it the way he wants, but like they say, "no man is an island of knowledge", it is never a shameful thing to add other people's wisdom to yours for better results, most especially when you feel you are in a cross road and don't know the right way to go.
