That a good idea " not your keys, not your coins" This is very important for anyone that is coming into crypto investment to know more especially newbies. So as for me the best advice I would give to anyone that wants to invest in crypto is not to invest more than what they can afford to lose. There are risk associated with crypto currency morespecially due to it's volatile nature so it can't really be speculated correctly. Also it will be unwise to allow our decision as regards our investment to be based on emotions and impulses. Before reach to any decisions we should make proper research to avoid making unnecessary mistakes that make affect or expose our investment to a great danger
You are giving the right advice and I agree with you. You should have a planned investment concept and tolerance for risk to use valuable capital properly. New investors want to see one side of a coin such as its positive or profitable but they do not want to face the reality about the back of the coin. For them, it should be made suitable for investment by conveying the basic idea of a thorough analysis of each aspect of investment so that they can accumulate and profit from the right coin in the future.
Long term investment and tolerance should be combined with discretionary income flow. Regularly buying the right crypto and expecting to get extra profit should not make oneself greedy. Long-term investment is valuable for a sustainable financial system rather than short-term trading. Gaining the ability to estimate the price of crypto for investment is valuable for an investor, so one should continue to buy regularly and stay connected to the market and gain experience in finding multiple sources of income.
