Sorry I don't understand what you mean by success doesn't come in a day based on hardwork or principles. If I may ask how can one be consistent without working hard cause I know this two work hand in hand to get a success and sometimes grace is needed to get this success cause I have seen people who are consistent and hardworking yet no success.
To settle down and make a thorough planning before investing in Bitcoin sounds like someone who wants to trade Bitcoin though it is good to make plans but the plan should be how much you want to invest so that it won't affect you to the extent of going to touch your investment when it is not yet matured cause Bitcoin investment whether you plan or not as long as you hold it for longer period of time you will definitely make profit so I don't think there's need for too much plans or analysis before investing in Bitcoin unless you want to trade, then you wait for the price to dip before investing.
If you have seen individuals that are very Hardworking yet no successful, that does not mean Grace can take the position of Hardwork before one is successful and probably they might be spending time doing the wrong thing in the name of Hardwork.
You are wrong for saying wether one plan or not as far as he holds, he would surely make profit, the how you want to invest is a plan, and comes along with discipline, consistency, emergency funds, discretionary funds, what to put in place which balances you on the journey of Bitcoin investment, allocated amount for accumulating Bitcoin, will guide one and not necessarily just holding.
Please don't get me wrong grace is for everyone and I believe to an extent grace is in part by part that is to say that you can have grace when it comes to appointing people that will benefit from a particular thing but you may not have grace when it comes to some other things and again Bitcoin investment doesn't need too much analysis or calculation most especially if one is investing for long term. Moreover, you can't enter a long term investment when one don't have something that will be sustaining him or her. In summary Bitcoin investment doesn't require too much analysis like when one wants to trade.
