You've listed some decent points, but personally I think it's heavily depends on what kind of trading you're planning on doing, shortterm(daytrading) vs long term trading(hodling). Personally I think the points you stated(a,b,c) are more towards longterm trading. When doing short term trading, I think it depends alot on hype/publicity/shills of a certain cryptocurrency. Let's use NEO(NEO) and Bitquence(BQX) as an example. They've been kinda steady on a low price in the past, but then alot of people on Facebook groups and on Reddit started shilling on these coins weeks to months ago, guess what happened? They skyrocketed, since everyone got too excited with the prices and started buying. This is also a perfect example of FOMO or "fear of missing out".
Thats a good point and one I wanted to incorporate in OP but left out to keep it simple.
Initially I set out to just buy and hold BTC and ETH (+1 year unless they come crashing down) but digging deeper into the crypto space I am now curious about trading in any time frame (I have the time).
What are the rules of thumb in terms of time intervals when people talk about short/long-term trading?
Nice examples. I looked up NEO and looking at the graph from the launch of the coin, the sudden increase is even clearer.
How do you handle a scenario like that? Say you notice a coin getting a lot of hype months after going steady and prices increase slightly do you buy in even if you dont believe in long term prospects but just to ride the pump and sell before the 'dump'?
On FOMO: When/how do you decide that you are late for the party?
There are no like "standard" time intervals when talking about short term and long term trading. Personally I think short term is like at the 1-4day mark, whereas beyond that, you can probably call long term or semi-long term depending on how long it is. Whereas buys and sells that happen in the same day are called "daytrades" or "day trading".
Honestly, personally I always go with my "gut feeling". If I see that it has risen up a bit but not too much and at the same time that certain coin is still getting so much hype, I'll most likely cash in a bit. And yes. Even if I don't believe in the coin, even though I think a certain coin is so stupid, I still cash in a bit and sell immediately at a certain point just to get a bit of profit.
The thing is, you don't. That's one of the beauties and dangers of crypto trading, is that it's almost impossible to know what the highest price can be, so it's also almost impossible to know if you're late or not. Sometimes I still go in even if I feel I'm quite late, but I only rack in a very small amount. Just for the shits and giggles. Again, go with your gut-feeling.
