It's not enough having an investment plan, knowing the right choice to make for every investment defines the investor better. Take for example jumping on every new coin we find on reputable exchange might not be enough guarantee that coin will do well in the future.
Some coin might have good Supply but low liquidity, some might have high market capitalisation but very poor volatility. Although it's hard to predict the accuracy of a coin performance in the near future this why it is always advised to stick to the known which is BTC.
Another option is to spread ones portfolio amongst different coins but ensuring the have a greater percentage in projects with a visible future. It is better to win small and lose less than lose more and win less
Okay @ OP, you have made some points.
I am going to generalize my thoughts on this as the topic and board is concerned.
So I am to take that power of choice making in any form of trades is first considered what to Invest on because otis business wise to engage on a business one is knowledged about and then environmental surveys is run to find a suitable location were your nature of trading is required and not just investing on any kind of business because it has been favorable and lucrative.
You also think about of the nature of the business is attracted to seasonal income so you can implement some marketing strategies so as to keep your trading firm actively productive.
Most of trading idealed investors who are business oriented who doesn't have a particular business ideal up the head sometimes are inspired to indulge on a particular business by the nature of what the environment is needed but doesn't have one around. This is were your creativity in creating incomes on untried businesses is activated.
It is investors decisions to decide if running a short-term or a long-term investment. All good about it is making profits rather being concious and taking earlier measures against retirements is a one considerations that is why a long-term investment and diversifications of investments is considered a business wise.
