Many times newbies are not going to be in a position to really invest either aggressively or ruthelessly, since they are likely ging to simultaneously build their various back up funds and to get into a bit of practice to make sure that they are used to putting aside some of their income for 4-10 years or longer.
I expected that newbies should always ensure that they invest and take enough time to hold, they may not go into any form of quick decision on selling than for them to have time while holding, i also don't expect a new to quickly ran into making trades, because they are not yet familiar with the system and how the risk could go on any attempt they made on trade.
But when we help them understand the importance of investment, how to buy and when to do so, they are going to quickly grab the idea and logic involved in this and then apply it, while they are still holding, they can proceed with their learning the more as they continue to develop a thicker skin towards investment and knowing many other strategies of investing on bitcoin, which they can later independently do by themselves later.
Even when newbies are familiar with the bitcoin investment system they shouldn't even for trading rather their focus should be on how to accumulate more Bitcoin and HODL for long, and this will make have more rest of mind when investing for long, it will also make new investors not to panic even when the price of bitcoin is dropping because their investment plan is to accumulate and hodl for long time with out thinking to sell believing or thinking the price will drop further instead they will use the dip as opportunity to even accumulate more aggressively if the money to so is available without over doing knowing that the price will increase again.
