First of all it doesn't take much knowledge to start investing in Bitcoin. Gaining knowledge can be essential to prolong and secure your investment. Secondly, one of the fundamental main points of investment is the source of income. If you have no source of income then I think there is no need for you to invest. I don't think anyone would suggest investing if you have no source of income, there is no question of investing with debt. This may be an act of sheer folly. To invest you must first have a source of income, which is surplus after meeting your and your family's needs or an alternative source of income.
The basic knowledge is enough for someone to start investing in Bitcoin once their sources of information are reliable. This ensures that later, they will not think of selling their Bitcoin unnecessarily. One thing to consider when investing in Bitcoin is to have emergency money set aside. In case any emergency arises, one can solve it using the emergency funds. Many new investors end up selling off their Bitcoin just because they don't have emergency savings. In fact, some are forced to sell at a loss due to an emergency and lack other means of getting the money to solve the problem. Emergency savings are always a good backup for Bitcoin investment, as it is volatile in nature.
People don't need to worry about they don't have enough experience to deal with bitcoin. What's more better they need to pay attention is on how they could start to invest on bitcoin. Since if they keep doing research and don't have confidence for their selves to start right away then I guess nothing gonna happen to them since its like they are delaying the whole process. I guess emergency funds should be consider less at first. Much better for them to settle up the funds intended to use for investment and once they calculate all possible percentage to use base on their earnings then by that they can start to pay attention to build up their emergency funds. What's more important is to start since for sure they provably got inspired more to do further research to increase their learnings also maybe to increase the size of their investment to get more better result in future.
