I think an effective HOLD strategy is needed, There are 03 HOLD coin strategies:

HOLD to target, sell
For example, buy BTC $ 3000 and only sell when BTC $ 15000, this is a buy and leave it to sell only at the desired price. This is the most basic and least effective HOLD way. Assuming BTC goes to $ 14800 and you turn your head, you might have to wait another year.

HOLD flexible
This is the most effective and optimal way for HOLD. The key to how this HOLD is centered on the number of coins sold at a time feels right.

HOLD long term
Long-term HOLD is mainly applied to investing in long-term projects / coins that you really trust. You can buy and wait until the market is saturated, as well as the market to make things clearer
