The little old lady draws her fib from the low to the high and sees a 90% + sale! She always looks for Cheap, cheap prices in crypto, but she can start nibbling at the 0.618 fib level, 0.786 and nibble at the 0.886 level. She never invests more that 5% in any one coin, less is more in this situation for her.
The old lady also looks for an asset that has flattened out beneath the 200 day MA.
She calls her "broker" and places an order for an amount @ Ƀ 0.00014249 Satosi's, She works out an average if she had more than one buy order and sells it when it doubles. She places her sell orders, and forgets, every time the coin doubles, half her holding gets sold. The first double was at At Ƀ 0.00028 she sold half, and at Ƀ 0.00056 she will sell half again etc.
This is not to be taken as investment advice! This is an investment strategy by @davincij15 at www.thedavincicodes.net And there are many more layers than discussed here.
Also @bbeamish at the rationalinvestor.com this is their strategy and you should get a course from them.
These are my ideas only.
