I would simply invest the $100 long-term and forget about it... then use additional fund held in stablecoin for gradually buying dips/lows, and probably selling high. This method usually turns out profitable especially on established crypto like Bitcoin... And it's not that difficult to learn.
Not difficult to learn, but hard to implement in reality. Typical example would be (I don't mean you, but the average trader) - you keep $100 for long-term, and have $100 for active trading ("gradually buying dips/lows, and probably selling high"). Then you put the second $100 into something, and price moves not how you expected. You sell (if smart, others will continue to keep - increasing the loss). Then you decide that it's time to re-enter and you are confident about that, so you take $20 from "long-term" because expect to earn $40 - enough to recover "long-term" fund + make money on active investment. Then you lose that also. Then with a strong desire to recover the "long-term" fund, you will take more risky and less reasonable bets thus magnifying your losses and faster depleting the overall fund.
Its not that difficult to learn but it would really require some time for you to take grasp even on the most basic or simplest idea of it.You wont really be able to do this stuff if you dont have the slightest idea
on how its done.
I dont believe on that 1% traders are successful because we wont be seeing soo much liquidity into this market on daily basis if there are lots who do losses up in the market.
This might be only applicable on other markets when it comes to chances but not into this market.There are lots who do make money and of course loses are much more in quantity than to those
who do end up on making profits.
Important thing is that you do sustain yourself into this market in utilizing price movement for your profit making opportunity.
True - not difficult to learn, but requires intelligence to implement correctly.
As for liquidity in the market - it's simply provided by market makers, and exchanges themselves on the coins they want to, that's why in most of the coins there's only minor liquidity. And you are correct - that research wasn't about crypto-trading, as the history of that is too short for now. But it was about all other markets. But I believe as the current crypto-traders are ex-FOREX, ex-stocks, etc. traders numbers won't be too different.
There is time value of money but if the coin is a well supported coin with good concept and utility there is no need to sell @$90 or $50. The best thing to do in this knd of the situation is to leave the investment and start a new one at the $50 price if have enough capital but if capital is an issue is better to sell @$90.
True - if you add time value of money, return will be way worse. However, most of the coins are without any utility or use - simply created for scamming people or for attracting traders. That's why it's gonna be hard to watch how the balance declines when the asset decline from $90 to $50, and you can't even sell that.
I think these 1% of the trader are those who have a proper financial management, who knows the difference between their assets and liabilities, who can segregate savings from investment and those who do not afraid to take risk and willing to get rekt but they will move forward and will continue to learn even they failed sometimes, I admit there were times that I don't want to trade anymore I just want to continue working and save it not to invest anymore or trade anymore but then this is just a part of the process that I need to survive.
Great point! Yes, financial management, risk management are some parts which most of the people forget about and think that simply learning chart patterns will make them rich

And the motivation is of course a great part - losses are unavoidable in the market, but being able to keep going despite of that is a valuable personal character.
